How would you like to open your AT&T bill and discover you were overcharged more than $1,000?

An AT&T-admitted “computer glitch” is routinely overbilling customers in Tennessee several hundred dollars a month for charges that are supposed to be included in their service plan at no additional cost.

One Clarksville woman has been getting bills nearing $1,000 a month every month since January, and AT&T is well aware of its mistake, crediting her bill each times she calls.

But Belinda Horton wonders what happens to other customers, especially the poor and elderly, who may not be up to scrutinizing their phone bills every month and aggressively pursuing credits from the phone company.

“This is crazy. This keeps happening over and over,” Horton told WSMV-TV in Nashville. “When I got the next bill, it was $921.”

Now she’s fed up.

“At this point, they can correct my bill, and then they can just keep AT&T,” said Horton. “Everyone needs to check their bills.”
