Credit card — SYNCHRONY FINANCIAL (PA)

Credit card company isn't resolving a dispute about a purchase on your statement. I have disputed my account balance since XX/XX/2023, during which time Synchrony has done an abysmal job of communicating clearly. Because of their failure to make themselves understood, this dispute has gone on far too long and has become far too complicated, particularly given the small amount in controversy. Since the last time I used the account for a purchase, in around XX/XX/2023, my minimum monthly payment had been {$190.00}. On XX/XX/2023, I paid ( via my bank account, as usual ) {$190.00} toward my next regular monthly minimum payment. Even after several days, the payment had not posted to my account, so I sent a message on XX/XX/2023, to advise of a potential problem with the payment. Sy
