FNB failure to address STI cancellation requests!

Here is a reply from FNB relating to my STI which I cancelled over more than a year ago as follows: 'Between 10 February 2024 and 30 Apr 2024, you initiated a debit order dispute. Unfortunately, due to a system issue, we could not process the fees for this service. The associated fees will now be charged to your account on 22 May 2024. We apologise for any inconvenience caused. For queries, please call ***. Terms and conditions apply. I am disappointed at the above feedback, yet my original request at canceling the STI of more than over a year ago still has not been met. I continually dispute the monthly debit order to no avail!!!!! I want lthe accounts and any other department related to this dipute to address my issue immediately at looking into why my initial cancellation request was never met and I insist on a full refund since the original date of cancelation!!!! I would also like to cancel my funeral cover as well as I do not receive the satisfactory responses from either an FNB branch or online Banker!!! The assistance of previous premium bankers were also to no avail as they would point you to the necessary department but I would receive no response or urgency on the matter!!!!!
