This is a SCAM!!! They are not Discover. I have a Discover card and have spoken directly to Discover. They only call from 1-800 number, they only call ONCE and never on the weekends because they are closed. Also, when they call, they ask that you go to their website and make a payment. Never take it over the phone. So please listen, this is NOT Discover!!!! If you answer, tell them that they are a scam and DO NOT call again or you will report them to the police immediately.
