Who called from 6078214179

11/30/15 - Received call from this number. When I answered they hung up.

12-01-15 - 8:18 pm. They did not day nothing, it was quiet at the other end.

At least twice a week (often every day and sometimes several times a day) I receive a call from this number on my work phone (which I have had for almost two months).  I answer and there is no one there and they hang up, I don't answer and a voicemail is left that doesn't say anything.

Repeated calls and hang up as soon as it is answered.

I get 30 calls a day from number 6078214179, I answer say hello they listen and never say anything. I want them to quit calling me and remove my number from their calling list, before I have to call the police to file complaints for harassment. I am a disabled person and do not have any student loans at this time. Please HELP!
