Called twice, once before 8:30 am and again at 12:18 pm. No message of course. Blocked number. It looks like it is from United Breast Cancer Foundation, not highly rated by Charity Navigator.
Caller ID shows 571-298-8288. Claims to represent a charitable organization. They are very pushy, with many repeated calls, even after being told to remove number from their calling list. One call occurred before 9:00 AM, so if you are home sick prepare for this morons to keep you from getting some rest.
They call my home number almost daily. Started around beginning of May 2016. (So for last 9 days.) I answered once (my mistake) so now I probably have years before they'll stop calling me. When I answered, no one spoke.
I've gotten a bunch of calls from this number as well as from one that caller ID's as Breast Cancer. I blocked that one; maybe this is their alternate annoying number. I tend to think calls like this aren't charities at all but are tests to see if the number is working before selling it to foreign scammers. Blocking this number as well.
