Incorrect Charges After Settlement and Failure to Close Account

I recently took the time to submit a compliment to FNB for the efficient handling of my retrenchment claim. Unfortunately, I am now compelled to lodge a formal complaint regarding the lack of resolution on my revolving credit loan settlement and closure. On 23 January, I contacted FNB to request a settlement balance for my revolving credit loan, as I was unable to settle and close the account via the app. The consultant advised me that the settlement amount was R177,068, which I immediately paid. I was then informed that the amount was 90 cents short, which I also paid, bringing the total settlement to R177,068.90. The consultant confirmed that everything was in order and advised that a request would be submitted to have the account closed. Despite this, on 24 January, additional charges of R2,917 ran on the account. These charges are not my fault. I acted in good faith, re**** on the settlement figure provided by your agent, and paid the exact amount required to close the account. Any transactions or charges that occurred after I was instructed on the settlement amount should therefore be reversed, as the account should have been closed following my payment. I have since followed up with agents on the chat and a banker, who has advised that the matter has been escalated to management. However, I am still awaiting final resolution. I do not understand why I am being penalised after making full settlement as instructed. The bank has received its settlement in full, and I expect the account to be closed without further delay, and all incorrect charges to be reversed. I have been waiting since 23 January for this matter to be resolved, and I request that it now be finalised urgently. I look forward to your prompt intervention and written confirmation that: The additional charges have been reversed, and The revolving credit account has been successfully closed. The bank should be happy to have recieved their monies i owe them
