I just got a call from this number. A woman who called me by name said I had been entered into the "Dream Come True Sweepstakes". She then wanted to confirm my address (which she already had) and I stupidly confirmed the information. She then went on to say that I would receive prizes and offered me subscriptions for free, but then said I would be charged 4.99 a week to add Us Weekly. I told her I wasn't interested, and she insisted on her offer and finally hung up. Although I didn't give her any new information, I did confirm my address. Should I be worried? Also, it concerns me that she already had this information. What should I do now?
