Who called from 2015201160

This number calls and no one on the line report it to the natioal do not call regestry. if everyone complains they will stop it

I get a call from this number at least twice a day with no answer when I pick up and when I call it back all I get is a fast bizzy tone.
What gives??

I also got a call from this number.  No voicemail left.  When I call back it is just dead air, and hangs up.  ??? any ideas?

I got this call today and got the same thing as other callers. Except instead of returning the call I put in the caller id and this is where it sent me

Caller asked "Is this (my full name)?" When I said "yes", he proceeded to give my detailed address down to zip code and asked if that was right.  When I said "yes" again, he then asked if I had diabetes.  At that point I objected to his asking for personal information and I asked him who the information was for.  He said that he hadn't asked for any personal information. When I said that his asking my name and address was personal. He sounded exasperated and said "If you'll give me a chance I'll tell you." I persisted in objecting to his asking me personal questions without telling me why.  He abruptly hung up.
