Unknown Name/Unknown Number calls repeatedly (often once per day and even at night) and either says that they want to lower my interest rates on my credit cards, lower my auto loan rates, or extend my automobile warranty ('Just press 1 to speak to someone about...'). I always press 1 and ask for company information or to be removed from their call list, and they always just hang up on me. Today I pressed 1 to talk to somebody about lowering my credit card interest rate, and pretended I was interested. I spoke to an operator who said her name was Whitney. She told me their number (800-847-2911) and said their address was Suite 300 W Peachtree, Ft Meyeres FL 23906. She said they just needed my credit card account information and they would lower my rates. She said that they are affiliated with Visa, Mastercard, Discover, and American Express and with all banks. I asked to talk to her manager. He said his name was Mike. When I asked how they found out about me, he said they got my number from Visa and Mastercard because we have a very high credit score and good payment history. When I asked him why his system often called us at night, he became agitated, asking what that had to do with me getting a better interest rate. I asked him if they used the Do Not Call list, and he became very upset, speaking to me in a rude tone, and insulted me for having 'nothing better to do with my time.' Then he hung up on me.
