While I was undergoing a credit check in order to obtain my XXXX license, it was discovered that I had a previously unknown collection account on my credit. I contacted the debt collector " Southwest Credit XXXX XXXX XXXX, XXXX XXXX XXXX, TX XXXX Phone XXXX '' and was told it was a debt to XXXX from several years earlier. I asked them for verification of the debt, however all they sent me was what looks like a blank XXXX bill with the amount they say I owe as a " previous balance. '' I called them back and they told me that that was all that they have and I would have to call XXXX myself. When I called XXXX I was told that they do not know what they debt was for and that I would have to get that information from the debt collector. I talked to Southwest Credit XXXX XXXX time and they were very curt and said " We gave you what we have, now you need to pay. '' While no one at either XXXX or Southwest Credit can explain what the debt is for, my fear is that they are claiming that they never got their cable boxes back. When I closed my account I did so in person and turned in my equipment, but for almost 6 months I got phone calls almost every day saying I had not returned my equipment. I always told the caller that I did return my cable boxes and they always said they would look into it, and then the calls would keep coming. At this point I do n't know what to do, I firmly believe the debt is not valid and neither XXXX nor Southwest Credit will provide me with anything to show that it is valid ... however this is seriously endangering my employment and if it is not resolved soon I will be force to pay it. I 'm basically being held hostage and robbed.
