I called back and requested to be removed from their call list and they said ok. This is some kind of fund raiser organization.
It comes back as "unlisted" on a reverse phone lookup. If I can't identify who you are I'm simply not going to pick up. Your loss.
If this is truly a call from Breast Cancer Research Foundation (BCRF) then they should call after 9am and leave a professional business-like message.
Got a call from this number. I called it back "breast cancer research foundation" came up as BCRF on caller Id.
