Scam! They called multiple times over the past month. I finally answered. The woman thanked me for my previous support for some Children's Leukemia association. I did not recognize the name. She then transferred me to another woman who asked for my c/c or debit card #. I said no but if you send me a pledge card with your non profit name and info I will mail a check. She asked for my name and address. I said if I had given to you before you should know it. I asked what is the name of your organization? She said I had to be transferred to someone else to answer my question. I hung up!
