I've had so many calls from this number that went to machine with no message. This latest time, I finally answered. It was a recording that asked me to stay on the line for more information. So, for fun, I did. A man came on and said he was with Credit Card Services and he could lower my interest rate to pay off my balances. I asked him which card he represented as I have several. He mumbled something about being a company working for all credit cards. I told him I didn't have any balances on my cards, and he called me a liar. He said everyone has balances, but I replied I pay mine off every month so I don't carry a balance. He called me a "f***ing liar" and hung up on me. So far, no more calls....
