Who called from 6109735064

They called my house on Wed 3-13-13  and my systems has not been the same.  I told them that I was a PI and then they hung up???

Unknown number called attempting to reach me and when I said what for they hung up

Same number called my cell twice on 7-10-2013.  I figured it was a scam because no message and only 5 people have my number which I have been using for 20 years.

Numerous calls from this number to my cell phone.  Music in background then a hangup.  Called back with one ring then a "non working number" signal.

Called my home number and received my voicemail. All I heard was music than a woman comes on asking for me by name then she hangs up???? No idea who she was. Continues to call 3 more times that day!!! No other messages were left after the first! Registered on the do not call list 2 weeks ago.
