I got a message on my answering machine and called back but they didn't ask for any personal information. They already knew mine and my husband's name and asked me to meet them in Rockland, ME to receive my prize this weekend? I don't remember entering any contest..

This number has called my phone & hangs up.  Also 312-488-1853.

A voice message was left saying that a sweepstakes that I entered for a Lincoln Navigator is over to call another number and congratulations was given........(Did not even say my name)  
The message was:
"Hi, this is Bill with the Prize Distribution Center. Calling in regards to the contest that was entered sometime back in hopes of winning a brand new Lincoln Navigator. Contest is officially over, we are looking at your entry forms, so we do have very good news for you.  What you need to do is give me a buzz back here in the office as soon as possible at 1-800-301-3436, again that's 1-800-301-3436. Ask for Bill when you call, and have a great day."

Calls and Hangs up.. tried to call it back and its busy..

Got the exact same message as IreneD.  I did not call them back.  Do they think I don't know I didn't enter any contests?  And do they expect me to believe that a fairy godfather randomly dreamed up my phone number to bestow a Lincoln Navigator on?  What an idiot!
