United Breast C
Can only presume what the C stands for. Left no message. Unsolicited.

This is one of those clever calls that you'd be easily fooled into thinking is a real person, but it isn't.  It's someone (from a froeign country perhaps, that doesn't actually speak English perhaps) operating a console that has a bunch of pre-recorded sentences from a female with an American voice. So they've got a hundred or so pre-recorded sentences and push the appropriate one depending on what YOU say and
try to get information out of you.  If you think I'm making this up, just ask them an off the wall question like, "You had a bad cold the last time
I spoke to you, what kinds of medicine did you take to make it go away?".  They won't be able to answer you.
Pretty sure that 480 454-7266 is a scam. The 480 indicates that this is a Phoenix area phone number but it's easy for scam artists to buy equipment that allows them to program in whatever phone number they like.  They could actually calling from anywhere on the planet:
Nigeria, Jamaica, Russia..........

I have been receiving unwanted calls from the United Breast Cancer Foundation for years now.  I have tried and tried to get them to respect my numerous requests for the calls to stop.  Hasn't happened.  I'm at the point of reporting them to media, law enforcement for harassment and the BBB.  I'm done being nice to their obnoxious callers.  Also from same foundation is 480-409-8023.

Do a search on call blocking devices and phones.If its a cell phone, there are free call blocking apps out there including trac & straight talk.

If these guys aren't crooks, I'll kiss your [***] on Main Street.
They call  incessantly.
They certainly are a scumbag organization; these calls are  harassment, pure and simple.
