Reported a dispute in regards to creditor XXXXLast year XX/XX/XXXX received updated corrected report showing zero balance. Recently received notification of charge off and pastdue balance. I disputed the account via mail with all supporting documentation. Including XXXX records title to vehicle, new owner information. On XX/XX/XXXX I called to inquire to why the investigation has been more that 30 days. 
I spoke with a rep named XXXX and he says that he would update the status to complete but failed to provide information on proof of outcome. 
I asked him to check the dispute history and he did verify the creditor XXXX XXXX updated the account to reflect vehicle being paid off last year. Now recently the account shows a charge off with past due balance of XXXX. which is not correct. 
I asked to speak to a supervisor with Equifax but rep XXXX stated his superior who 's name is XXXX said they ca n't update the account regardless of any documents I sent. But they ca n't furnish any documents to how they verified the account.
