Disconnect their service
What Cablevision should do and I have seen them do to another customer when I used to work there that called in to much requesting certain channels. Just disconnect their service, hopefully Fios isnt available in their area so they will have to have all separate service providers for tv internet and phone. Put them on a lifetime ban or until they drop this silly lawsuit. I have many issues with Cablevision but I think they did the right thing here. My inlaws got power restored the day after Sandy, their Cable services came back for 30 mins then out for the next week and a half, they came back this past Sunday. If Cablevision did a blanket credit they wouldnt get credit for those additional days.
