Imagine if your electric utility billed you for service based on a meter that was developed by the company, had no third party verification, no oversight by a Bureau of Weights and Measures, and wrote provisions into the company’s terms and conditions that allowed the company to terminate your service if you complained too much about the resulting bills.

Rethink possible.  AT&T.

When America’s largest phone company implements its arbitrary and unjustified Internet Overcharging scheme this May, it will bring its controversial usage meter to bear on every one of its broadband customers — a meter implicated in wild over-measurements of customers’ broadband usage — usage that will put customers perilously close to, or over the limits AT&T wants to establish.  The result?  Fat additional profits in the form of $10 overlimit penalties for every 50GB AT&T says you consumed for broadband traffic that costs them pennies to deliver.

The broadband usage meter is no stranger to controversy and lawsuits over accuracy issues.  Despite reflexive denials that a particular provider’s usage meter couldn’t be wrong, far too many have had to backpeddle and confess that the meter that should have measured $40 in usage and resulted in $4,000 bills instead “was in error.”

Whether providers are developing meters that are just flat inaccurate or are quietly putting a virtual finger on the scale to increase the opportunity of overlimit profits is unknown, but past history shows the meters typically overmeasure usage, not undercount it.

Without independent verification and ongoing oversight, some customers wonder if AT&T is sticking a virtual finger on AT&T's usage scale.

Some recent past history:

• Telstra is Australia was implicated in December for a wireless usage meter that occasionally reported more than three times the usage measured by wireless phone owners’ built-in usage measurement tools.  Company representatives ended up crediting some customers as much as $3500AUD in inappropriate overlimit fees that should never have been charged.  Complaints continue to arrive as late as February about overbilling;
• Telecom New Zealand’s usage meter overmeasured usage this month resulting in overcharges and throttled speeds under the ISP’s “fair use policy.”  One customer was billed for 27GB of usage during one overnight period, despite the fact the computer was switched off;
• BT in the United Kingdom confirmed it overbilled some of their broadband customers in February when their usage meter measured usage for customers who had switched their computers off or took them away on holiday.  As far as BT was concerned, those computers were still at home and still racking up web usage.  Only last week, the company finally confessed their meter was inaccurate — overmeasuring usage that never happened;
• AT&T’s counterpart in Canada — Bell, cannot manage to measure customer usage correctly either, so it suspended its usage tracker tool temporarily.  In February, one customer tired of overbilling proved a point when he took his computer to the United States just to guarantee it could not go near Bell’s network.  The result?  Bell said he used 500MB anyway;
• In February, a class action lawsuit was filed against AT&T for “overmeasuring” wireless usage in some instances by up to 300 percent;
• Last fall, Verizon was forced to refund $25 million dollars for phantom data usage charges for service many customers claimed they never used.

In virtually all of the prior incidents, a common pattern emerges, usually ending when providers fall on their swords, admit error and issue refunds:

• Phase 1: Initial denials from providers there is a problem with the meter, usually blaming the customer, the customer’s measurement tool, or the process used instead;
• Phase 2: Once proven to be an issue, an effort to downplay its significance and impact with claims that only a “tiny” percentage of customers were affected;
• Phase 3: Refusal to submit usage meters, wholesale costs, and other components of Internet Overcharging to third-party verification;
• Phase 4: Refusal to allow an independent audit of customer accounts to verify overbilled customers were properly refunded every penny of excess charges;
• Phase 5: Class action lawsuit or government investigation commences;
• Phase 6: Settlement reached with refunds or low value coupons to customers who take the time to request one;
• Phase 7: Report excess profits from unclaimed refunds on balance sheet.

In too many cases, multi-billion dollar telecom companies that rely on those meters to measure and bill customers for their usage were implicated not for undermeasuring usage, but overmeasuring it — often substantially.

Some AT&T customers are already disturbed with what could be history repeating itself.  A reader of Broadband Reports in Skokie, Ill., compiled his own detailed analysis and found AT&T’s measurement tool grossly overmeasured his usage, and even worse, couldn’t do simple math and overmeasured him again when adding up his daily usage totals:

AT&T said that I had used 361GB in a single month! Surely this couldn’t be right. I’m a heavy user, but every time I even so much as glanced at my usage stats they’ve always been in the 200GB range. Surely something was amiss, so I decided to dig deeper.

It’s an old habit, but the first thing I do when I suspect something is wrong with any bill is enter all the line items into a spreadsheet and add them up myself. It sounds like busywork, but sometimes you’ll catch unlisted charges that have been phantomly added to your bill, or occasionally an outright math error. I couldn’t believe what I found. AT&T’s usage meter results insist I had used 341.39GB down, and 20.18GB up. But when I added all the daily detail entries (the DSL equivalent of a call log), only 332.8GB down and 0.72GB up are accounted for.

AT&T is claiming that I used 361.57GB of data, but according to their own daily data I only used 333.52GB, an 8.5% overcharge.

This AT&T customer discovered AT&T overmeasured his usage far more than it undercounted it. (Lines above the baseline show downstream traffic AT&T overmeasurement; lines below show undercounted usage. Click to enlarge.)

In total, this particular customer reports his usage was overmeasured by a whopping 33 percent. He is not alone.  A robust thread of similar results is active on Broadband Reports.

AT&T’s response to the early criticism follows the same path taken by other providers, starting with denials.

“We’re addressing ways we can make the labels and information on the online metering tool more clear for customers between now and May (when the new policy goes into effect),” said AT&T spokesperson Seth Bloom.  “I can also assure you our team is performing checks everyday to ensure accuracy.  That said, we believe we have an accurate tool.”

“Other tools may measure at different 24-hour periods than we do, and most likely do not take into account the standard network protocols (e.g. Ethernet, IP) that are used to provide applications and content to our customers via the Internet.  As you know, this is fairly standard to incorporate when measuring broadband traffic and is applied by other ISPs who measure usage.”

Customers and columnists alike are worried about AT&T's new data limits. This Milwaukee Journal-Sentinel columnist is not thrilled, and neither are customers who overwhelmingly want unlimited broadband access.

“In the end, AT&T expects the caps to impact only the aforementioned 2% [that comprise its heaviest users].”

With the right level of over-measurement, virtually anyone can be a member of the “2% Club.”  One customer told Connected Planet AT&T was already overmeasuring her DSL account by as much as 4,700%.

How can you measure your usage to compare against AT&T?

“It’s not hard to maintain independent usage statistics to double-check AT&T’s numbers,” says the Broadband Reports reader in Skokie. “If you have a DD-WRT compatible router, it will keep your upload and download history automatically. If you don’t have a compatible router, you can still run WallWatcher or MRTG to get the total bandwidth used by your router. Finally, if your computer is connected directly to your DSL modem without a router, you can run software like Net Meter to track your internet usage.”

Customers inconvenienced by unnecessary usage meters which threaten to expose them to unjustified overlimit fees is just one more reason why we call out these Internet Overcharging schemes.  Call AT&T and let customer service know you intend to switch providers if AT&T implements their usage cap scheme in early May.  Tell them regardless of what kind of usage you incur each month, you cannot afford the chance AT&T’s apparently inaccurate usage meter could expose you to a higher bill.  Tell them you don’t want the hassle, and the only way you will remain as a customer is if they do away with the entire scheme.

Broadband Reports has obtained a leaked memo stating AT&T plans on eliminating its flat rate broadband plans for DSL and U-verse customers effective May 2nd.

On that date, AT&T will limit its DSL customers to 150GB per month and its U-verse customers to 250GB per month in what will be the largest Internet Overcharging operation in the nation.  Customers who violate the usage limits will face a three-strikes-you’re-overcharged penalty system.  After three violations of the usage limit, customers will pay an additional $10 for each block of 50GB they consume.  Although that represents just $0.20 per gigabyte, less than some others have imposed, it is not pro-rated.  Whether a customer uses one or fifty “extra” gigabytes, they will face the same $10 fee on their bill.

Customers will begin receiving notification of the change in the company’s terms of service March 18.

AT&T claims only 2 percent of their DSL customers will be exposed to the Internet Overcharging scheme.

“Using a notification structure similar to our new wireless data plans, we’ll proactively notify customers when they exceed 65%, 90% and 100% of the monthly usage allowance,” AT&T’s Seth Bloom told Broadband Reports. The company also says they’ll provide users with a number of different usage tools, including a usage monitor that tracks historical usage over time, and a number of different usage tools aimed at identifying and managing high bandwidth consumption services.

“Using a notification structure similar to our new wireless data plans, we’ll proactively notify customers when they exceed 65%, 90% and 100% of the monthly usage allowance,” AT&T tells us. The company also says they’ll provide users with a number of different usage tools, including a usage monitor that tracks historical usage over time, and a number of different usage tools aimed at identifying and managing high bandwidth consumption services.

However, AT&T’s accuracy in measuring broadband usage is open for debate.  The company is facing a class action lawsuit over its wireless usage billing.  According to the suit, AT&T consistently inflates usage measured on customer bills.  No third party verification or oversight of usage meters is mandated — customers simply have to trust AT&T.

AT&T ran trials in Beaumont, Tex., and Reno, Nev., from 2008 with a range of usage limits.  Customer reaction to the trials was hostile, and the test ended in early 2010.  In December, FCC Chairman Julius Genachowski told providers the agency was not opposed to usage limits and consumption billing schemes, leading some to predict the green light was given to companies willing to test whether customers will tolerate Internet Overcharging.

AT&T claimed this weekend its new pricing was going to benefit customers.  So long as customers keep paying their bills, AT&T will not “reduce the speeds, terminate service or limit available data like some others in the industry,” Bloom said.

But the usage limits come at the same time Americans are increasing their consumption of online video and other high bandwidth services.  Usage limits which may appear to be reasonable at first glance become punishing when they do not change over time and customers increasingly risk exceeding them.  Once established, several companies have repeatedly lowered them to further monetize broadband service usage.  AT&T has delivered some of the lowest usage limits in the wireless industry, so it has faced customer criticism in the past.

Customers tied to existing term contracts may likely avoid the usage caps temporarily.  Others will not stick around long enough to find out.

“I will be canceling my U-verse service on Monday and go back to Time Warner Cable,” writes Stop the Cap! reader Jeffrey.  “I will never do business with a provider that imposes overlimit fees on usage that literally costs them next to nothing to provide.  It’s like charging extra for every deep breath.”

Some of our other readers are headed back to Comcast, which has a 250GB usage cap, or exploring DSL provided over AT&T lines by third party companies, which likely will not impose usage limits, at least for now.

“Charging 20 cents per gigabyte isn’t too bad, but you just know AT&T will lower the caps or jack those rates up,” our reader Ian writes. “It is very important to send AT&T a message right now we are prepared to quit doing business with them over this issue, or else we will be nickle and dimed to death by them tomorrow.”

Our reader Jared asks whether new legislation has been introduced to curb unjustified Internet Overcharging.  In 2009, then Rep. Eric Massa (D-N.Y.) introduced a bill to ban Internet Overcharging unless companies could prove it was justified.  At the moment, there is no new legislation, but when providers attempt to overreach and impose pricing the vast majority of broadband customers oppose, that could change.

At the moment, Stop the Cap! recommends AT&T customers begin to explore alternative providers and prepare to terminate their service with AT&T unless they scrap their Internet Overcharging scheme.  AT&T earns billions in profits from their broadband division and spends millions on lobbying.  With this amount of largesse, AT&T does not need this pricing scheme to remain profitable.

Suddenlink, one of America’s smaller cable operators, has been undergoing a transformation as it tries to meet expectations of today’s cable subscribers and match whatever phone company competition comes their way.  While some of the upgrades are customer-friendly, others pose ominous signs for the future — particularly with respect to Internet Overcharging broadband customers.

Let’s explore:

The Good — New Broadband Speeds, New DVR, New Investments

In parts of Suddenlink’s service area, particularly in Texas, the company is moving most of its cable service to a digital platform.  This transition is designed to open up additional space for more HD channels, keep up with broadband demands, and open the door for additional on-demand programming.

In Nacogdoches, Suddenlink announced it was adopting an all-digital TV lineup.  Starting this week, the company is offering subscribers free digital adapters — also known as “DigitaLinks,” to enable continued viewing on analog television sets that do not have a set top box or digital tuning capability.  Every subscriber purchasing more than the broadcast basic package (that only includes local stations and a handful of cable networks) will either need a digital tuner-ready television, a set top box, or a DigitaLink device to continue watching.

What is good about this transition is that Suddenlink is not charging customers a monthly fee for the adapters, either now or in the future.  That contrasts with other cable companies like Comcast and Time Warner Cable that have handed customers a set top box or a digital adapter they will begin charging for after a year or two.

Suddenlink expects to invest nearly $120 million this year in Texas, and by the end of the year will have invested nearly a half-billion dollars in the state since 2006.

Texas is extremely important to Suddenlink.  The third largest cable company in Texas serves about 450,000 households and approximately 27,000 business customers in Amarillo, Lubbock, Abilene, Bryan-College Station, Midland, San Angelo, Georgetown, Tyler, Victoria, Conroe, Kingwood and Nacogdoches.

Suddenlink's New TiVo DVR

The company has also lit new fiber connections to handle data communications, primarily for business customers, and is upgrading its broadband service to fully support DOCSIS 3, which will deliver faster speeds and less congested service.

Customers in the state are also among the first to get access to a new and improved DVR box built on a TiVo software platform.  Suddenlink’s “Premiere DVR” service ($17/mo) is now available in Midland, Floydada, Plainview, Amarillo, Canyon, and Tulia.

The Bad — “Suddenlink Residential Internet Service is for Entertainment” Purposes Only

The Humboldt County, Calif. Journal's "Seven-o-heaven" comic strip commented on Suddenlink's problems. (Click the image to see the entire strip.)

Do you take your broadband service seriously, or is it simply another entertainment option in your home?  If you answered the latter, this story may not be so surprising.

In Humboldt County, Calif., broadband users started noticing their favorite web pages stopped updating on a regular basis.  At one point, a blogger in McKinleyville noticed he couldn’t manage to post comments on his own website.  But things got much worse when several web pages started reaching customers with other users’ names (and occasionally e-mail addresses) already filled in on login screens and comment forms.

It seems Suddenlink started to cache web content in the far northern coastal county of California, meaning the first customer to visit a particular website triggered Suddenlink’s local servers to store a copy of the page, so that future customers headed to the same website received the locally-stored copy, not the actual live page.

But the caching software went haywire.

Web visitors began to receive mobile versions of web sites even though they were using home computers at the time.  Some were asked if they wanted to download a copy of a web page instead of viewing it.  And many others discovered websites were customized for earlier visitors.

While the caching problem was irritating, the privacy breaches Suddenlink enabled were disturbing, as was the initial total lack of response from Suddenlink officials when the problem first started in late January.

The Journal finally reached a representative who provided this explanation:

Suddenlink Senior Vice President of Corporate Communications Pete Abel knew that a cache system had recently been installed in Humboldt County, but was unaware of the particular problems reported by users. After speaking with the Journal and other Suddenlink employees, though, he released a statement explaining what appeared to have happened.

According to the release, the cache system was installed in Humboldt County on Thursday, Jan. 27 — the very day that users began experiencing problems — and was intended as an interim solution to relatively low Internet speeds in Humboldt County. The system, it said, was able to cache only unsecure websites — those which, unlike almost all reputable banking or commerce systems — do not encrypt communications. But the company eventually discovered the problems that its customers had been reporting and, having fruitlessly worked with its vendor to find a solution, turned the system off on Monday.

“The good news is that secure Web site pages will not have been cached,” Abel said in a follow-up call to the Journal. “And I have been assured 100 ways from Sunday that never would have happened.”

Andrew Jones, who runs a blog with his Suddenlink broadband account, tried to opt out of the web caching and received an interesting response, in writing, from a Suddenlink representative.  He was told he could not opt out of cached web pages with a residential account because, “the residential service is for entertainment only.”

Jones was told he would have to upgrade to a business account to escape the cache.

“If a small local radio station intermittently went off air for multiple days, the radio host would be apologizing and explaining the situation,” Jones wrote the Journal. “If a large utility company experienced sporadic power outages, people could hear a recording on a toll-free number to learn the cause and about ongoing repairs. What does an Internet provider do when web access becomes spotty and begins serving customers old copies of web pages? The company gets back to you in a couple days and suggests you pay more if you don’t like its recently degraded services.”

The Ugly — Suddenlink’s New Usage Meter Suggests 43GB is An Appropriate Amount of Usage for Standard Internet, 87GB is Plenty for Their $60 Premium Package

Although Suddenlink has not formally adopted an Internet Overcharging scheme of usage caps or metered billing, the company is sending automated e-mail messages to customers who exceed what they call “typical monthly usage for customers in your package.”  The e-mail tells customers they may be infected with a virus or someone else could be using your connection without your permission.  Boo!  For the uninitiated, this kind of message can bring fear that their computer has been invaded, either with malicious malware or the neighbor next door.

Customers have also received letters in the mail from the company telling them to check out their new “usage meter.”  Several have been sharing how much they’ve racked up in usage during the month on Broadband Reports.  One customer managed 243GB while another looking at the company’s super premium 107/5Mbps package managed a whopping 786GB.

Although the wording of the message has strenuously avoided telling customers they are wrong for this amount of usage, the implication is clear to many: they are counting your gigabytes and identifying the outliers.  One customer called it Suddenlink’s “You’re actually using your connection, and we really wish you wouldn’t”-message.

“No one with an ounce of sense would pay for a 20/3Mbps connection and only use 78 GB in a month. Let’s hope they’re just making cute suggestions, not easing us into a cap, because that just won’t fly,” wrote one West Virginia customer.

Another in Georgetown, Texas did the math and made it clear 43GB better not turn out to be a cap because it means customers can barely use the service they are paying for.

“It’s way too low. I got 10Mbps [service] because of price/value and not because I use less than 43GB,” he writes. “[Even] if I downloaded at 1.25MB/s for 30 days straight (1.25 * 2592000 seconds) I could [still] grab 3.164TB.”

Meanwhile, some controversy over the quality of Suddenlink’s service during the upgrade process had some residents in Cushing, Okla., up in arms at a recent city meeting.  Lorene Clyde complained Suddenlink’s “new and improved” service is worse than ever.

“I’m tired of paying for a service I’m not getting,” Clyde said.  “And the Suddenlink commercials – they are like rubbing salt in a wound.”

KUSH-AM reporters were on hand to cover the event, noting Clyde was not the only one complaining.  The radio station noted that “the buzz around town echoes her sentiments – from the ‘mildly irritated’ to the ‘downright mad’ – citizens have been complaining.  Not only have they been complaining to Suddenlink – as difficult as that may be (the call center is in Tyler, Texas) – but to city leaders.”

What Clyde and others may not have realized is that Suddenlink officials were in attendance and were able to apologize for the problems, but a growing consensus among consumers and city leaders is that a broad-based refund for the poor service was warranted.

Commissioner Joe Manning said while he appreciated the promise to figure out the problem, it wasn’t good enough to just apologize and promise – that subscribers’ bills should be adjusted to reflect the poor service.

Commissioners Carey Seigle and Tommy Johnson agreed with Manning.  Seigle pointed out it would be “good P.R.” to give some sort of rebate across the board to subscribers while Johnson complained that the original “upgrade” was only going to take a few weeks and now 8 months later – things are not better, but worse, noted the radio station.

Suddenlink officials on hand said they did not have that kind of authority, but continued to promise things are going to get better.  “I pledge to you,” one said, “We will find it [the problem] and fix it.”

KJTV-TV in Lubbock, Texas talked with Suddenlink about the growing trend of neighbors “borrowing” neighbors’ unsecured Wi-Fi networks.  Other than the accidental recommendation that consumers should “invest in Internet spyware” to keep your computer safe, the report does a fair job of shining a light on a practice that could have financial consequences if the provider implements an Internet Overcharging scheme.  (2 minutes)

Meet Daniel and Kate Methot, proud owners of $5000+ in Bell data charges the company cannot explain.

A couple from Merritt, B.C. has received bills from Bell for more than $5,000 in data usage, even after the skyrocketing bills made the family so frightened of their phone, they turned it off.

This is the story of Daniel and Kate Methot, who purchased a smartphone from Bell in October of last year.  When the first bill arrived, it contained more than $1,000 in data charges.

“My wife looked at me and I thought ‘Oh boy, what did I do that I didn’t know that I had done? I am in trouble’,” Daniel told CBC News.

When Internet Overcharging of this magnitude occurs, most people first blame themselves, assuming they did something wrong.  The Methot family figured they downloaded a malfunctioning or data hungry app or left something running on the phone.

“We never thought we would be billed for something we weren’t using. That was sort of a new concept for us,” Daniel said, but the family still sought guidance from Bell on how the charges could get that high.

“They really couldn’t give us an answer,” Kate said.

The family deleted everything they could find on their new Samsung Galaxy phone in hopes of stopping the surprise charges.

But when the December bill arrived, the couple was horrified to discover their new bill was more than $3,500 — almost entirely for data usage that literally cost Bell pennies to provide.  In fact, the phone company managed to bill the couple for 30 hours of usage during one 24-hour day, a clear warning sign there was a severe billing problem at work here.

But when it comes to protesting charges with Bell, the Methots discovered customers are guilty until proved innocent.

“I felt like I was being treated like a criminal — like we were trying to essentially steal from them,” Daniel said. “When you call in to argue a bill, that’s what they do. They tell you to pay — and don’t ask questions.”

Kate got a stern lecture from Bell telling her to quit watching videos on her phone all day long.

Of course, the couple denied doing any such thing.  In fact, by the time January arrived, both Daniel and Kate became afraid of even going near their phone, much less using it.  The couple routinely shuts the phone off when they are not actually using it for calls, but still the data charges kept coming — more than $5,200 to date.

CBC News asked Bell several times for a response to the Methot’s complaint. While refusing an in-depth interview on the topic, Bell told CBC News it cannot yet explain what is happening with the account.

That hardly inspires confidence for the Methot family.  Despite Bell being unable to explain the charges, they continue to insist on being paid for at least some of them.

The couple even hired a lawyer for $400 to send a letter to Bell demanding better answers or the couple would not continue to pay the unexplained charges.

In that case, Bell would simply turn their account over to collections, and potentially ruin their credit rating.

Bell’s theories about the stratospheric bills include:

• They are running up the bill themselves and now trying to run away from the charges they incurred;
• They are using the phone’s Wi-Fi hotspot feature, inadvertently allowing the entire neighborhood to share their connection;
• They are watching Netflix all day and into the night;
• They ran across the border into the United States and are incurring roaming charges;
• They are tethering their computer to the phone and that consumes massive amounts of data.

The one explanation Bell hasn’t imagined is that their billing system is completely fouled up and their usage meter cannot be trusted.  One might imagine Bell could actually determine where the phone is being used, to dismiss the roaming theory.  Plus Daniel reports he is incurring data charges even when the phone is completely powered off.

Finally, Bell admitted they were responsible, credited the account for more than $3,000 of the charges, and the Methot family thought their long nightmare was over.

Only it isn’t.

Merritt, B.C.

Days later, though, they received a bill with $1,204 in new charges.

“It was just a temporary relief and then the stress is back again,” Kate said.

“At that point I wasn’t interested in being a Bell customer anymore,” Daniel added.

On top of that, Bell has reneged on their apology, now claiming they were not responsible for the faulty charges after all.  The Methot family can pay their $1,200 phone bill with cash, check, money order or credit card.  And if they plan to leave, they better be ready to cough up the early termination fee as well — another several hundred dollars.

Isolated incident?  Don’t bet on it.

“These customers are not alone,” Howard Maker, the head of the federal Commissioner for Complaints for Telecommunications Services told CBC News. “Unfortunately, Canadian telecom consumers do suffer from many billing errors from their providers.”

Maker said his office received more than 1,900 complaints about wireless providers last year, and 40 per cent of them were about overcharging.

With Bell insisting customers can trust their usage meter — the one that generates $5,000 in data charges for one family alone — Canadians should prepare themselves for the bills that will follow. With no oversight agency able to monitor the accuracy of the meter, Bell customers will just have to take their word for it.

CBC News talks with the Methot family about their Internet Overcharging experience.  (5 minutes)

A snake in the grass?

You used 50 kilobytes of data visiting a web page on your iPhone, but AT&T claims the site actually consumed six times that — 300 kilobytes, for which the carrier overcharged you for access.

A major point of contention for consumers facing Internet Overcharging schemes is that the same company with a vested interest in maximizing revenue from such schemes also administers the meter that measures how much you used.  There is no oversight or independent verification.

In a lawsuit filed this week, AT&T Mobility faces accusations it is systematically overcharging iPad and iPhone users for data services many never used.

Patrick Hendricks claims AT&T’s Internet Overcharging “was discovered by an independent consulting firm retained by plaintiff’s counsel, which conducted a two-month study of AT&T’s billing practices for data usage, and found that AT&T systematically overstate web server traffic by 7 percent to 14 percent, and in some instances by over 300 percent.”

The lawsuit compares the company’s billing system to a gas pump that charges for a full gallon when it only dispenses nine-tenths into your tank.

Hendricks’ suit also claims the same independent testing firm confirmed AT&T charges for data usage even when phones and iPads were disabled for data sessions, push notifications, location services, and other data features.  After 10 days, the firm found AT&T had billed 35 data transactions totaling 2,292 kilobytes of usage, akin to being billed for gas when you never even pulled into the station.

The complaint admits the individual overcharges are relatively small for most consumers, but collectively they earn massive profits for AT&T.

“AT&T has 92.8 million customers. In the fourth quarter of 2010, AT&T reported its wireless data revenues increased $1.1 billion, or 27.4 percent, from the year-earlier quarter, to $4.9 billion,” the suit claims. “A significant portion of those data revenues were inflated by AT&T’s rigged billing system for data transactions.”

The lawsuit is seeking class action status and refunds of alleged overcharging for impacted customers.

The firm handling the case, Bursor & Fisher, has tangled with cell phone providers before, winning cases against Verizon, Sprint and T-Mobile.  The firm is also exploring a lawsuit against Sprint on behalf of Evo owners who paid a $10 surcharge on top of an “unlimited” data plan.
