I had an account with XXXX in XX/XX/XXXX, I closed the account but was late with the final payment. However did pay the full amount XX/XX/XXXX. For some reason they are showing the account late 90-120 days in XXXX and XXXX of this year XX/XX/XXXX. I have disputed it, XXXX said that they confirmed with them the account was closed XX/XX/XXXX and paid in full but they will not fix it. I have called several times over the past few months and been very patient waiting but today after 30 minutes on hold and discussing it with a woman identifying herself as XXXX and a Supervisor in Pennsylvania she would not fix it. I asked to do a XXXX way call with XXXX and she refused. It is an obvious mistake but all she said she would do is dispute it again which I have done 2 times. When I asked for her supervisor she hung up on me. 
It is only Trans-Union that is reporting this incorrectly. I have spent several hours over several months trying to rectify it. XXXX said there is nothing else they can do to correct it as they have sent the correct information. 
In my previous calls I would have to speak with multiple people from XXXX and give them my personal information over and over which made me uncomfortable. No one I spoke with would give me any kind of employee number and everyone would tell me something different. 
Please help me. I has dropped my credit score XXXX points
