I get calls from these people all the time. I have no outstanding debts and I don't have cable. They keep changing their phone number. I've received calls from: (718) 569-7956; (732) 941-0190; (516) 323-2641. I have blocked all these numbers. With VoiP, you seem to be able to spoof your numbers and ID anytime you want to fool the callee into answering.
Received 5 more calls from this number today. No name listed, so did not answer. Also, since I am in New Jersey, and if they are in the Hudson Valley, do not know why they would constanly be calling me. Never leave a message, either. So they can keep calling and I will keep not answering.
They called me twice so far. If they're a collection agency why won't they leave a message? Who are they collecting for? Who do they represent? (I've never had an account with cablevision as previous poster mentioned) No name, number, account or claim number to refer to? I don't trust that, so I will continue to let them go to voicemail until they can clarify why they're calling.
