I also got a call from Premium Gifting stating I have won one of 3 top prizes for entering a contest to win a car.  Also said it was the last time they would contact me.  I checked it out online...seeing it was a scam I thought I'd call them back (866-933-6013 ext 109)  just to see what they had to say.  They gave me a claim number, said I had to go to a local address for World of Getaways (The address she gave me was for a Holiday Inn Express.) either tomorrow night or Thurs.  Long story short, I selected a day and time.  She asked me to confirm that I was married and our income was over $50,000. I told her I wasn't married but that my income was well over the $50,000.  To my disappointment she said I couldn't go. :-)  But...I could have a married couple pick it up for me.  Just have them call the number I had called.  Right.
I am on the do not call registry also.  I'm wondering if they got my info because I do own a timeshare.
