This company calls with threatening overtones.  Will not tell you who they are or what the debt is. You may not ask any questions.  When I asked who they are and why they think they can just threaten anyone, I had no debt with them, the girl on the phone became condescending and flip. She insisted that the ph# may have belonged to someone else before to which I said, I have had the # since 1987.  She "turned me over to the supervisor" who announced himself as Daniel White and he IS the company, then he corrected himself by saying he ran the company and the Fed Gov't gave him the right to collect the debt in any manner it takes.  As I tried to ask again who are you and how was my phone number given to him, I was told to shut up and allow him to speak I may have a turn later. He spoke and when I tried to tell him I was not Karen Miller and know no Karen Miller, he told me I was wasting HIS time. I would say this event has wasted several hours of my time. He would not give me the company name and did not give me my chance to tell him what I thought of his process. It is frightening to receive such threatening calls that they will make decisions that will effect my life without my knowledge and the Gov't tells them they can do this, but has not informed us of how to defend.  I will be contacting my Congressperson and BBB
