got one exactly like your description.  offered me a free 3 day getaway to anywhere in the states if I subscribe to whatever magazine and give my credit card info.  Red flags flying when they asked for that, so I said I didn't have my card with me and hung up.  I'm not answering again if I ever see that number.

they've called me twice a week for at least 4 weeks now. i finally answered today-
its some sort of "Dream of a Lifetime Giveaway" with visa/mastercard/discover or something. they tell you all the things you can win if you enter and yadda yadda...
theyre extremely rude when you ask to be taked off the list and removed from the call logs
she didnt even have my name right and she wanted me to give her all kinds of information over the phone
