Automated message claimed to be from Marriott Hotels and that my phone number had won $999 towards my next stay, press 1 to receive more information. So I pressed 1and the guy who picked up immediately asked whether I was 30 or older. I said I was requesting more information and he pushed again about the 30 or older. I said I wanted information about why he was calling me since I am on the Do Not Call list: he hung up.

I would have no qualm about saying that it was a fraudulent call intended to get something like a credit card number out of me. See http://news.marriott.com/2015/01/marriott-res ... -in-canada.html
