Very noisy, hard to understand message, but caller seemed to ask whether I remembered entering a sweepstakes a couple of months ago. Since I NEVER enter sweepstakes, this was obviously a scam.

No winnings- just STEALING YOUR MONEY.  if you said you had entered a contest - they would then tell you won and had to pay money via Western Union to receive your winnings - ILLEGAL!

excerpt from FTC CONSUMER ALERT
A Dozen Ways to Protect Yourself
The next time you get a "personal" letter or telephone call telling you "it’s your lucky day," the Federal Trade Commission encourages you to remember that:


1.Legitimate sweepstakes don’t require you to pay or buy something to enter or improve your chances of winning, or to pay "taxes" or "shipping and handling charges" to get your prize.


If you have to pay to receive your "prize," it’s not a prize at all.

Grainy, hard to understand, recorded message asking me if I remembered filling out a sweepsteaks some months ago.  If I had, and if I'd won, I would expect to be notified BY MAIL, not by PHONE.  In any case, they shouldn't have my phone number to begin with.  THIS IS CLEARLY FRAUD!
