FNB Credit card, poor division

Good day, I am now writing again on this platform about the persistent poor customer service of FNB. Just for a brief background, I was caught with ********** credit card purchases up to the amount of R 75000 after the case was reported to FNB's ***** line, the credit card division still had the audacity to recover a credit card payment from my Cheque Account of R 5800, pending the investigation. Well, a portion of the transactions were paid back to me and my credit card was again on a good balance. So, on the 5th of September 2022 I make an incorrect inter account transfer from my Cheque Account to my credit card, immediately I call credit card to please just put the funds back into my Cheque Account. I follow up with another request on September 7, 2022. Of course, as expected with the poor service from FNB and no correspondence from them my request was not adhered too. I'm tired of the credit card department just *****ing money as they please and the client always having to get the short end of the stick. So, I withdrew my R 3 100 from my credit account which they failed to allocate the money after my request, now I’m threatened with bad credit worthiness and lawyers. But until today did I not received any correspondence from them, even after logging a complaint at the branch as well, I have a list of reference numbers and e-mails that have not been answered until today.
