I would not advise calling that number: the experience is not pleasant. I have yet to make it successfully through to the end of the process, to no-call Nirvana. And if I ever do, they’ll just start calling me again after 11 months anyway. Basically, never give Cablevision your phone number, because once you do, you’ll never get them to stop calling you.
