Got a call from this number 3/22 and they claimed to be a company working for major banks and credit cards. They said that by using my credit card I was entered into a raffle to win $25,000 or other big prizes. Of course I was immediately suspicious but all they wanted to do was verify my address so that they can inform me of the results by mail. They recited my address and I, maybe stupidly, confirmed that it was correct. I did not think that they could do much damage with only a address that they already knew. Any advice?
