Received letter through US Postal Service. The letter did not have a return address on it. The winnings was strange because I did not register with this company. There is something else that seem strange, and that was there are two different companies that is involved in claiming your winnings. It was also strange that a Martin-May, and, Carols Fernandez names appear on some other scams, and, one of them have the same dollar amount as your winnings. The documents are not very professonal for the type of companies they claim too represent. After reveiwing both documents there is something about them that places "??????" within your own mind. I have been taken before with this type of scam before with regards too SHELL OIL COMPANY, and, if you don't play, how can you win!!! Stay safe investorgate for your own good.
