Seems to be the week of scammers calling. Got a call for this number shows caller ID Breast Can SF call back to add to "Do Not Call List" says it a disconnected number and I blocked it thru comcast. Be aware people are trying to get money out of you no matter what. Disrespectful especially that my mom passed away from Breast cancer.
This is very definitely a scam. I have received this call numerous times recently, once per day, as late as 11pm, and as early as 6:30am. The caller is an automated voice response service that is designed to sound like a real woman, but that actually navigates you through a menu. If you stay on long enough, you might be able to talk to a real person. Attempts to call the number back result in a phone system "disconnected number" message, so unlike with many telemarketers, you cannot simply call back and have your number removed from their system.
