Problem with a company's investigation into an existing problem: Credit card

I am filing a formal complaint against Synchrony Bank regarding my CareCredit account. I experienced a one-time payment oversight due to an unexpected health management issue, marking my very first missed payment in my entire history with this institution. As soon as I became aware of the issue, I immediately brought the account balance current. I contacted customer service to request a one-time goodwill removal of the 30-day late reporting mark under standard corporate accommodation rules. Frontline agents stated they were unable to assist. Because this is a singular, isolated incident on an otherwise flawless account history, I am formally requesting that a Synchrony corporate compliance officer review this file and submit an electronic " Automated Universal Data '' ( AUD ) deletion form to the major credit bureaus to wipe the 30-day late notation.
