Said she was from the credit card dept. Asked about the debt on my card (which card she could not answer). I asked how do you know I have debt, she said your records say you have debt. I said that is none of your business, put me on your do not call list. She said that wouldn't do any good. Asked about a supervisor, she said he was not there now. I insisted there must be a supervisor and I wanted to speak to them. finally she got tired of me insisting my credit card was none of her business and she hung up. Some kind of a scam, just don't know what. Caller did have a indian accent.
