Same scam.  Except I won the Graduating Center sweepstakes.

This is the number on my caller ID, with a robo call saying I won the Great Outdoors sweepstakes giveaway (of course I did not enter it). The message says to call Tony Roberts at 877-370-4433.  If you look up that number, there are many who report the same call I got. I'll be reporting this to the Do not call website.
