Same thing here, very suspicious!!!!

I received a message on my machine and then an actual call stating that I had entered a sweepstakes and won 3.2 million dollars and a Mercedes.  They even sent me an e-mail of the documents.  2 U.S. Marshalls and their attorney would deliver my winnings AFTER I went down to Western Union and paid a fee of $449 dollars.  If when they got to my house, I decided I didn't want my prizes, I could go back to Western Union to get my money back.  Hmmm...sound suspicious to you?  The call was from Gold Rush Inc. Hotel Casino on 304 Carson Road, Las Vegas, Nevada.  He had a heavy accent and told me that he wasn't going to pressure me to do anything, but I could call back if I decided to accept the prizes.
