Lowering interest rate scam. First call was from 678-618-1372, got a second from 786-671-3404, and finally 319-225-2089. They kept asking me to read my whole card number for them to verify I was the card holder, which I refused to do. When I asked them to remove my number from their list and stop calling me the guy laughed. Sooo, don't talk to these creeps!
