This company knew my name and tried to have me agree to give money to a Leukemia fundraising effort. I said that I was not interested and I would like to be removed from their list. I asked if that was ok and the caller said "no that is not ok" and hung up.
6146563373 has called me every day for the last couple of weeks. They never left a voicemail, and I've since blocked the number, but they're still trying. Every. Day.
