Robo call - "Would you like to lower your credit card interest rate?" - Press one. We did this and were connected with a person. When we asked what credit card they were affiliated with, she replied Visa, Mastercard and Discover. I had to tell her to stop her speel 4 times before she would stop talking long enough to tell her we were on the National Do Not Call list. As soon as I got those words out, she hung up on me.
