Paying monthly fee for closed credit card.

This bank is ran by a kabal with gangster rules not FICA. Initially I didnt have a credit card so when I app**** for one my monthly fees 'bank charges' increased and December 2024 was paying R480 pm. In January, I closed my credit card account and cancelled my credit card. The monthly bank fee still remained the same to this date. Why is it that my bank charges didn't decrease when I closed my credit card account ? I want my money back for all these months. NEDBANK offers more benefits for less the bank charges on the similar account. This bank ****s me 😭😭😭😭😭 FICA please help!!
