USA Direct promotions representative in are will deliver the 245111.40 check to your door after you complete the claiming process.  Please call asap to start your calim process and activate your check.  Bob Martins, Claim Manager 1-778-709-9496.  I called Mr Martins, he instructed me to deposit check in my account and to tell no one, and call him back the next morning at 10 am.  I called him back the next morning and told him I had deposited the check.  He then instructed me to go and withdraw 3200.00 from my account.  That the prize representative and UPS would meet me at my home the next day with my prize check but I would have to pay the UPS man 3200.00 in cash.  In the meantime I needed to go to Western Union and send 1900.00 to a company in London. I told him no.  He lost it on the phone. He kept telling me he was stopping payment on the 4888.60 check.  I told him to go ahead I would get him for writing a fraudulent check.  He is repeatedly calling me wanting his money back.  I explained to him that it was not his money, it was a check made out to me.  I am not for sure but I think I scammed the scammer. but he just kept insisting that I tell know one.  I knew it was a scam as soon as he said that, but I just had to play along.  I love messing with their heads!!!  The Letter has Ronald L Blake listed as VP of operations.  It also has a pin # you must give them when you call them.  The check I recieved was drawn on JPMorgan Chase Bank, NA , Syracuse, NY 13206. The City of New York Department of Social Services, Public assistance account.  Mr Bob Martins speaks with several different accents.  Like I told him on the phone, I am not going to pay you for me to win money, he tried to rationalize that the money I was paying his company was from the check he had sent me.  But it still does not seem legitimate.
