This happened to me too. I would donate to breast cancer so I asked them to mail me the information and she said she needed the information over the phone. I hung up after that.
Called a private cell phone. Breast Cancer money grabber. Lady hung up on me when I asked how she got my number. Would never give to this organization if they called again.
My wife received a call from this number asking for someone else. When she said it was a wrong number the person said "maybe you could help me" and went on about raising money for breast cancer. As she received a call earlier from someone asking about money for veterans she said she thought this was a scam. The person hung up.
