I got a call from "Shawn Jones" today saying the same exact stuff, referencing a Household Bank credit card account I had charged off back in 2004 when I was laid off and lost my job.  He pulled the same scheme, saying he was calling the client to see what amount they could settle, and I was actually going to settle it for 40% to not worry about it anymore, but when I started asking for straight answers as in which collection agency owns the debt he would not give me a straight answer.  He also used the subpoena line with me, and basically he started saying that Mastercard owned the debt.  He got very defensive when I started asking questions before paying and then he started raising his voice saying how it was apparent that I was uncooperative and did not want to settle the debt so he is going to proceed with the subpoena.  I hung up.  This seems in total violation of the Debt Collection practices act and I am super annoyed especially since it is out of the statute of limitations in California.
