Product: Credit reporting, credit repair services, or other personal consumer reports

This is not a duplicate nor is this complaint being filed by a third party, I am filing this complaint myself. Please see this complaint is processed to the letter of the law. 
I have a loan with DEPT OF ED/NELNET. I have always made my payments on time. For some reason, I realized that there was a late payment on my credit report. The confusing part for me is it doesnt reflect anything except 120 days past due. Ive never been behind on my payment. I tried contacting the 3 Credit Bureaus and the DEPT OF ED/NAVIENT but they have provided me with nothing tangible which reflects anything verifiable, as required under Section 609 ( a ) ( 1 ) ( A ) Disclosures to consumers [ 15 U.S.C. 1681g ] ( ( a ) Information on file ; sources ; report recipients. XXXX shall, upon request, and subject to 610 ( a ) ( 1 ) [ 1681h ], clearly and accurately disclose to the consumer. If the consumer to whom the file relates requests that the first XXXX digits of the social security number ( or similar identification number ) of the consumer not be included in the disclosure and the consumer reporting agency has received appropriate proof of the identity of the requester, the consumer reporting agency shall so truncate such number in such disclosure. & Section 611 ( a ) ( 1 ) ( A ) Procedure in case of disputed accuracy [ 15 U.S.C. 1681i ] ( a ) Reinvestigations of Disputed Information. If the completeness or accuracy of any items of information contained in a my file at XXXX is disputed by the consumer and the consumer notifies the agency directly, or indirectly through a creditor, the Bureaus shall, free of charge, conduct a reasonable reinvestigation to determine whether the disputed information is inaccurate and record the current status of the disputed information, or delete the items from my file in accordance with paragraph ( 5 ), before the end of the 30-day period beginning on the date on which the agency receives the notice of the dispute from the consumer or creditor. There is definitely an error with their part. I was never late ( XX/XX/XXXX and XX/XX/XXXX ). Investigate properly and please update for 100 % accuracy.
