Got a call from this number. Any idea who it could be?

It's the "Women's Cancer Fund."  Robocall

With the scam going where people are trying to capture a "yes" voice print, that they should use a Robo call that mimics a person, and actually asks  "is this Susan? "  especially when one is awaiting cancer testing results!  I will never give them money ever as they have employed this prophetic method of fundraising   Too bad if they were legitimate, because of their methods they're off my list for any future consideration.

No worries.  They aren't legit.  This is a scam masquerading as a charity.  That's why they chose a name that's very similar to that of a real existing charity.  Try to find this organization online -- you won't.  Real charities don't hide.  They want to get as much attention (and as many donors) as possible.

The phone number has changed several times, but they comes up as Women's Cancer Center".
