Time Warner Cable’s new owner is reneging on a promise to keep offering cheap broadband, a consumer group said Tuesday.

Charter Communications, which bought TWC earlier this week and is in the process of rebranding it as Spectrum Cable, is rolling out its new pricing in the New York area this week.

But customers might have difficulty finding the low-cost $14.99 Internet option.

Phillip Dampier, head of StopTheCap, a pro-broadband watchdog group, said Charter was “supposed to keep ‘Everyday Low Price Internet’ for $14.99.”

But “good luck finding it,” he said.

Spectrum claims it does, indeed, offer low-cost broadband — despite it not being clearly listed on its Web site.

Also, Dampier points out that former TWC MAXX customers were receiving fast Internet speeds of 300 Mbps, but Spectrum’s new package offers speeds of 100 Mbps.

Dampier intends to file a complaint with state officials. He calls Charter’s action a “bait and switch.”

Charter, headed by Tom Rutledge, acquired TWC for $60 billion earlier this year along with smaller operator Bright House. It recorded a 7.4 percent rise in revenue in its most recent quarter, to $10.04 billion, and a profit of $189 million.

Spectrum is offering three triple-play packages, ranging from $90 to $130. Stand-alone Internet is advertised as $39.99 for the first 12 months.

A rep told The Post that legacy TWC customers won’t lose their packages, but once they end they can choose between a “retail rate” or Spectrum’s new packages, which are a “better value.”

TWC had pulled out all the stops to retain subscribers ahead of its acquisition by Charter. It rolled out so-called “retention rates” to keep customers — but now those rates are expiring and much higher rates are kicking in.

Spectrum says it is adding 20,000 employees as part of a decision to bring call centers back to the US.
