The caller identified herself as one fundraising for the International Fellowship of Christian and Jews. This # was not the 800 number I had ID'd in my phone, but she said it was a call- out number only. Anyway, she said that I could go to the website to verify the 800 number she gave me if I felt uneasy donating again / talking to her...which I did, and it was as she said. She was professional throughout the call.
