It was Doctors Without Borders. They were calling because I had made a recent donation and they wanted to know if I would be interested in being a monthly field partner (i.e., make a small monthly donation). She just thanked me for my support, gave a spiel about their work, and asked for a monthly donation or if I wanted to receive more info in the mail. Not a huge deal.
This number calls repeatedly and never leaves a message. Picked it up tonight to hear at the other end of the line, "We are from an organization that you support. We will call at a more convenient time." Crazy!
