Recently I complained about XXXX XXXX XXXX wrongly reporting an issue that has been solved years ago, so I contacted this office, after the investigation XXXX XXXX corrected my credit information, thus my credit score, Equifax did the same, but few days latter Equifax went back to the old numbers, saying that they are still investigating.My question is, if XXXX XXXX accepted my explanation and their investigation proved that I was right, how come Equifax is not accepting the same explanation, more over, correcting my score then rolling back again.Please help. Thank you.PS. I do n't know how to attach documents, such as letter from XXXX XXXX, unless I can mail it.
