Said I was a guaranteed winner of one of 4 prizes if I came to their office and did a tour of the company - A Lincoln Navigator, a TV, a vacation or $2500 cash.  Believe this to be a potential scam.

Just got a call from this number, 9:55am Arizona Time. Same as above, left voicemail from the "Prize Distribution Center." They stated that I had won a prize in a sweepstakes I had entered for a Lincoln Navigator. I will not be calling them back.

CAller said I had entered a contest an i was winner. Said I left some entries on the form blank. They needed to know if I was married. Told him I don't think so, if you need info send me a registed letter. He hung up.
