This person called me, would not identify themselves, saying I entered a drawing for $20K. Told her I am not interested and do not live in 520 area code any more and she said she would "call back later"; I replied "do not call me back" but she hung up on me.

Called on my cell phone.  Calls are increasing on my cell.   I can't help but think Verison sold my number to scamers when I change companies.

A bright and cheery sounding young woman from a land far, far away (I could barely hear her over the crackling line) was pleased to inform me that my number was randomly selected to be enrolled in a contest to win 20k!! Oh, joy, I told her, right before requesting she remove my number from consideration and cease from ever contacting me again.

Just got a call from this number claiming that they were from direct buy and that my number was registered to win something.  I asked that they "unregister my number and never call back.
