Complaint sub-issue: Their investigation did not fix an error on your report

Dear Equifax ; XXXX  and XXXX ; ***SEE ATTACHMENT PLEASE*** I'm a very concerned consumer here! I am actually shocked about the validity & accuracy of your recent investigation of this account that is reporting on my credit report from XXXX XXXX of being late on XXXX XXXX and XXXX XXXX. Last month I requested an investigation because I felt as though the item was not being reported legally and completely. Couple of days ago I received a letter stating that your investigation was complete, and you've determined that the account is reporting accurately. Basically, saying that it's accurately is a binding contract that you've conducted a thorough investigation and that can be perjury to the law. Look at the attachment for example, and you will see missed Credit Limit, inconsistent payment history and account status, incorrect and incomplete information on OPENED DATE, and 3 different dates for last payment ; and according to the recent report, it looks like that on XX/XX/XXXX Equifax said that i was OK with the payment, but however, XXXX  and XXXX  said that i was late. How are these factors and dates incorrect and inconsistent across the board. Can not be late but yet be on-time?
