FNB NON EXISTING SERVICE - I AM A PENSIONER

On the 4th Feb 2025 I requested settlement figures on a credit card "Thank you for affording us the opportunity to service your banking requirements. Please find attached Credit Card Settlement Letter as per your request. Should you have any further enquiries, please contact us on the details below: I settled in full, send all the details by email It is now the end of July 2025 They never closed the card, started adding interest on interest and taking the amount from my account every month It is not a debit order so I cannot even stop it I have contacted them in writing every month with no response Last week I phoned and the phone was dropped after 3 requests for the person's name on the other side. FNB stop taking money that is non existing and return with interest what you took so far Your service after 15 years stink
