Two Cablevision customers in Nassau and Suffolk counties are the lead complainants in a $250 million class action lawsuit filed Tuesday in New York State Supreme Court alleging the cable operator is illegitimately charging customers for service knocked out by Hurricane Sandy.

The suit claims that unlike other cable and phone companies in New York and New Jersey extending automatic service outage credits to impacted customers, Cablevision is only giving credits to customers who self-report outages within 30 days.

Cablevision was the hardest hit cable operator in the region, with its coastal service areas on Long Island, Connecticut, and New Jersey receiving the brunt of storm surges and wind-related damage. At least half of the company’s three million customers were without service after the storm hit Oct. 29. Nearly 80,000 customers are still without power and utilities are signaling some may wait until after Christmas before lights are back on. Some of the most devastated areas are not scheduled for restoration at all because those properties will have to be abandoned or rebuilt.

The plaintiffs claim Cablevision, “only agreed to rebate some of its most favored customers on a discretionary basis and in varying amounts, and only after the customers’ contacted Cablevision for the rebate.” The suit also alleges customers threatening to cancel service are getting the most generous rebates.

The suit suggests Cablevision should have known not to bill or accept money from customers that remain without service. Many Cablevision customers are on the company’s electronic billing and autopay programs, which will continue to deduct money from bank accounts for services customers cannot actually receive.

“The lawsuit misstates the facts and is without merit,” Cablevision said in a statement. “But lawsuits aside, we have an extremely broad and customer friendly credit policy following Sandy. Blanket or arbitrary credits for cable outages could shortchange customers because each case is different and our policy covers the entire period of time when Cablevision service was out, including when the service interruption was caused by the loss of electrical power.”

Cablevision says the amount of damage to its facilities is so extensive, it could impact the next quarter’s financial results. Company officials also admit some of their customers will not be coming back because their homes and businesses no longer exist.
