I want to see if these are the people who keep hounding me about credit cards.  I'm on the Do Not Call list but that doesn't keep them from calling at various times of the day.

These people call me every day, sometimes more than once. The called ID says cancer fund. I have begged them to stop calling me, even asked for them to send the info by mail, as I never give money over the phone. They persist in calling, do they think by calling me so often that they will eventually trick me into giving them money?
