On   XX/XX/XXXX  I ran my credit report from this agency. On that date the agency reported my credit   score to  be a  XXXX  according to their  FICO  calculation method. On   XX/XX/XXXX   the agency reported my  credit score  to be  XXXX  except according to their same report nothing had changed  EXCEPT  that, 8 months previously I had a late payment on an account.     I immediately printed my report to look for the offending account, so I could dispute it as I HAVE NOT had any late payments on any accounts in years. When I printed it, there was nothing. No new accounts had been posted showing late payments, no old accounts had been posted showing a late payment. Everything on the report was EXACTLY AS IT HAD BEEN on my   XX/XX/XXXX  r eport EXCEPT tha t   XXXX    credit inquiries had been removed and my revolving balances had decreased by {$13000.00}.     I then Called my report provider and asked them if there had been a report update, they asked that I wait until   XX/XX/XXXX   to see the next report ... I did. At this point my report was EXACTLY as it had been on   XX/XX/XXXX  , except   XXXX  i nquiries had been removed and my balances had decreased by {$13000.00}, yet there was still the erroneous report that 8 months previous I had made a late payment and therefore my score had decreased ... YET THERE WAS STILL NO BALANCE ON MY REPORT REFLECTING A LATE PAYMENT!     I immediately called Transunion and spoke to a  manager in the " Special Resolution  Department '' name  XXXX   XXXX . I asked  XXXX   XXXX   XXXX  why my report was stating that I had a late payment 8 months ago and she said " I would have to give her an example ''. I told her I could not provide an example because the report that her agency provided to me did not show an example. She then said " You have a bankruptcy '' to which I replied the bankruptcy had been on my report since   XX/XX/XXXX .   She then said I had a " collection account " that I then replied had been on there since   XX/XX/XXXX  as well. She then admitted " there is no late payment on your report but ANYTHIN G can affect your  credit score.  I ca n't tell you why we are reporting there is a late payment on your report unless you give me an example ''. I then reminded  XXXX   XXXX   XXXX  that her agency did n't provide an example in its report that I could show her and she said " all I can do is send you a credit report but there is nothing I can do for you ''.
