WM FINANCIAL GROUP / National City Bank WM Financial Group sent me a letter w/ a $3,900 Check. " a Consumer Reward Program Lottery" Brooklyn New York

I received a letter from these people and the envelope was sent from this address: 2901 Royal Lane, Niagara Falls, On N6H 4W1. I looked everything up on line with whatever information I had. I didn't find anything. They stated that the draw was held in June 2008, and that they tried to contact me several times. They also stated in the letter that for security reasons I keep this on the low. The claim must be in by August 2008." I called the # two times, The first time the voice mail was full, the second time a male picked up, He had an accent that seemed to be a little difficult for me to understand. He stated that it will take time for the $ to get through but to call once the $ has gotten deposited into the account. Is this for real or is my instinct correct?
