Winners Company
Received check for 4, 775 dollars.taxesof 2, 950 I called they took claim # from me and told me to cash the check. I haven't yet. What is the scam?

I recieved a check today (5/7/09) from the winners co. inc. The check has a Mrs. Winners logo in the top left-hand corner with an address from Atlanta GA beside the logo. The check is for 4, 775 dollars and the letter with the check says i, ve won 250 thousand. this check is to pay the applicable taxes of 2, 950. It claims that i will receive the balance after the taxes are paid. the letter said to not cash the check until i called. I called and gave the claim # to a claim agent and she then said that I could go to the bank and cash it and then call her back. I did not go yet. What is the deal here? thanks, Dennis
