Its a bogus call. I got same. And I also, on the same day, from the same Cablevision CT office, got a PRIVATE CALLER show up on my caller id, confirming a so-called appointment for a failed service that I supposedly reported! And you cannot call the number back -- its always busy!
Sorry to disappoint you people, but this is not a bogus person nor caller. It is a Cablevision Dispatcher who is looking to contact you to ensure you are home, prior to him sending someone to your house. If you don't pick up, then they will send them to the next service call. I picked up and spoke to him. That's why I know. This information is current as of today, Dec. 6, 2009.
