I received a message on February 3, 2012, saying that I won 2.5 million dollars and a Mercedes.  The name of the person that left the message was Beverly McDonald.  I called the number and left a message and I was returning the call.  About 1 minute later I received a call back from a man.  He went into details on how I was chosen as a winner.  He listed about 10 different ways, one being that I shopped at Walmart and I was entered into a drawing.  He proceeded to tell me that 2 FBI Agents, 1 attorney, UPS truck, and a wrecker (with the Mercedes) would be at my home tomorrow at 12 noon.  He informed me that I would need to make sure I had my ID when they came, as well as a money card from either Walmart, Walgreens, CVS, and several others.  I was to go put $499 on the card and contact him back and give the authorization numbers that would be put on the check.  This was suppose to be as an insurance so the bank could verify and be able to cash the check tomorrow.  When I told him I would not do that he then said he would have to inform the mega million people that I would have to forfeit the prizes.  I told him that if I had won, then I wouldn't have to do anything other than show my ID, and I told him I thought he was just trying to scam people.  He just kept saying that he understood how I felt.
