I went to Columbia grad school but have never been in touch with them as an alum. This is the second SUNDAY in a row (and third time in two months) that this number has called me and not left a message.
Told me she was calling from my grad school, Columbia Univ, and asked for my updated address and donation of $250. I asked to verify that she is calling from my school and said I can write a check to school as needed. She insisted I give her my credit card information and pay via paypal. It just sounded very shady.
