Black listed, whilest my account is paid up

I was a discovery member until last year June. And after termination, I was told I used the whole`s savings in 6 months and thus I needed to pay back the money. Which I had an arrangement in place for and it was paid up. Today I went to my ITC report and I am listed, by discovery and I cannot purchase anything..<br> <br> Are you kidding me??? I paid in Full, why am I suffering now. I have to run to the police station write endless affidavits and send proofs to Trans union. All whole day is has been interrupted because somebody didn`t do their work. Building a credit rating is hard and now I need to start from zero because of discovery.<br> <br> <br> Fix this!!!!
