received call to lower interest rates. pressed 1 to continue call. caller kept referring to "your credit card" rather than a specific branded card. Asked if I owed more than $3,000. I told caller they should know whether I do or not. further asked which card they were calling about and they gave me a list...none of which I have. When I asked why I was getting the call since I have none of those cards, I got "M*ther F*cker, F*ck You, Hang Up". I kept asking questions and they hung up.
