If its a scam, its a well orchastrated one: www.breastcancerpreventionfund.org. No one here even mentioned the info available here or on a number linked sites. Its understandble to question it because of the scams out there, but in this case I think they are real. Please prove me wrong, otherwise I'll help pay for a mammogram.
3/1 silent caller. I have no idea who this could be. Probably friends of the other 800 callers who I no longer answer. There people refuse to take "wrong number" as legit & continually phone.
UNAS may stand for unanswered
There was no one on the line. I called the number back and received an answering machine for The Breast Cancer Prevention Fund. How they came up with UNAS I have no clue.
