Total Scam

I was contacted by someone representing Card Member Services Visa and Master.  The "card" was left off the "master" because the caller did not use this.  The supervisor stated the first 4 numbers of my Discover card and my interest rate.  I then disclosed to the supervisor that I had lied about having a Discover Card.  He asked me why I was being an "[***]".  I told him that he was trying to scam me and that an actual business would not talk to me that way.  He then told me "to go [***] myself you [***]".  I told him that I would if he did first and then I ended the call.
