An anonymous reader quotes a report from Reuters: New York filed a lawsuit on Wednesday accusing Charter Communications Inc of short-changing customers who were promised faster internet speeds than it could deliver. The lawsuit in State Supreme Court in Manhattan accused Charter's Spectrum unit, until recently known as Time Warner Cable, of systematically defrauding customers since 2012 by promising and charging for services it knew it could not offer. At least 640,000 subscribers signed up for high-speed plans but got slower speeds, and many subscribers were unable to access promised online content such as Facebook, Netflix, YouTube and various gaming platforms, the complaint said. The lawsuit seeks "full restitution" for customers, as well as hefty civil fines. Among the allegations in the complaint was an accusation that Time Warner Cable leased older-generation modems to 900,000 subscribers knowing that the modems could not achieve faster internet speeds.
