Who called from 3107840563

Received a call from this number, but they hung up before I could answer.

Got a call from this number, a gentleman said that he is calling from sunny California and that I won a sweepstake. When I asked him where he got my cell number from he said from my credit/debit card company.

This guys is calling me all the time, and after I asked him to stop, he keep calling me..

I frequently keep getting calls from them, and usually I always miss the call. When I try to call back they never answer...what the heck is going on?

I asked him to take me off his calling list and he never called again.
