I was on another call when this number tried to ring through, caller ID said New Jersey so I didn't answer. They did not leave a voice-mail so a few minutes later I dialed them back...."Number is no longer in service"!
After Hearing that and reading the other comments I think they have to be a scam "company" with computer bots(?) random dialing... Plus where I live there is one cable company with no other options or competitors, wooded country area, so I will have FUN answering their call if they call again!  

Direct tv also gave them my. Number ....

Called.  Leaves no message.
