708-808-3204  No message left but caller ID said David Johnson

I got the same thing except a different person to call back.  Did you call back?  What did they say?

Got same call from Jeff today while out.  From number 708-808-3204 with name David Johnson.  Said from Prize Distribution Center for the Gran Sweetstake Giveaway.  Said I need to call the center directory, David Mitchel.  I haven't call, as I have been trying to find out if it's a scam.  Found this site and similar posting with with same format but different names and numbers.  Haven't found any posting with anyone who has gotten anything.  Found several postings that this was a scam, but without background why.  I would like to hear from someone who has call and what was the result (with details, not just 'ya, I got the car.....'
