Adverse disputes not attended

I've been disputing an adverse listing since August 2025, all my disputes gets closed due to pending investigation or canceled due to duplication or insufficient information. I've submitted all statements to show account is up to date, the account is even being overpaid and your staff are canceling my requests because they cannot differentiate between an arrears amount and advance amount. Credit provider confirmed they never got even a single email to confirm status of the account yet my requests are being canceled. Provider has also sent multiple emails to your investigation mailbox and no one has even responded let alone acknowledge in order to fix this. Please help this is not fair
