Robo-call for breast cancer. Unknown if you can opt out since have not been able to get that far. While I am not against giving to charities, I do not give to the charities that are constantly calling me, trying to make me feel bad if I don't give, do-not give  me an option to opt out and call me frequently (often more than once a day). When they spoof the number it screams fraud and any professional fundraising group that uses those tactics should be shut down. The number that caller ID showed was south-east Ohio number but the name was a Dayton Ohio car dealer. (Yells fraud).
