Who called from 3126255511

Got one this Sunday morning 8 a.m. And have gotten quite a few in the last month.  Only dead air. Today when I called back I got a busy signal.  Before I got nothing.

Got a message from here, 2:00, 9/30/13. They left a message about a lottery prize I had won. I was supposed to call them back at some 800 number. Since I never enter those, it is most likely a phishing scam.

Called picked up by answering machine.  Caller hung up.

Call and when you answer, they hang up.

Voice mail message left on my phone that the 50k sweepstakes was over but had good new for me  ask me to return call to 866 no for details.
