I received the same call yesterday on my cell and at work. the first guy was a Mark Johnson and I was told that some one from US Cash was going after me for fraud an I was going to be arrested. I wasn't thinking start and gave them $300.00 which was half of what I owed to them. he would not let me off the phone until I went to get the pre paid card and I should have known then that it was wrong. then I spoke with a Duane McGuire a collection rep which said once I paid this he would call me back with confirmation number the next morning. I did ask some questions but again I was so out of it that I didn't think the process through. I then received a call this morning from Duane again stating that the collector would not accept my $300.00 then want it all. I asked him to send me something with this information and he said he would once I paid. I did some research and found out that this was not true at all. I think part of the reason they got my name, cell number, work number and ssn# was from the internet. I will be calling them back and telling never to contact me again and I want my money back or i'm going to sue them for millions  of dollars. Stupid stupid me
