FNB taking my money after settlement was paid

i am have the most poor and frustrating time with FNB trying to close my credit card. i am being sent from pillar to post with no assistance on getting this account closed. everyone i am talking to cant seem to close this account and even after the settlement amount was paid on 29 January 2024 in full with extra credit, a debit order still went off. i went in to the branch with promises of the account being closed today, but instead of that happening, interest fees were charged, service fees were charged and account fees were charged, this is after a settlement amount was paid and closure of the account was requested. i received a settlement letter with an amount, which means all fees should be included as i wished to settle te account, withing an hour of receiving this settlement letter i paid the full amount plus a bit extra for incase there is fees, but no more was needed. i am a client at FNB for more that 15 years now and never ever have i experienced this type of service until now that i wish to close my account. they are steeling money from me. currently i paid over a R1200 more than what the settlement letter stated with the interest, service, account fee and debit order that went off. today i requested to speak to a manager, big and long promises were made that they will call me... well guess what, it is now 19:03 and i have not received a call. i am so so so upset that my bank, that is suppose to protect me as their client os busy *****ing my money and coming with stories that this is a credit card rule .. seriously...i have photos and screenshots of interactions with the chat services people also with no help. i want my money paid back and i want my freaken account closed 😡😡😡😡😡😡😡
