Private Banking Service Sucks!

My account was debited on 27 Sept 2023 with my credit card payment. The credit card was paid and on the 1st of Oct there was a remaning amount, as usual, after the necessary deductions were made. On 5 Oct 2023 I noticed that my payment was then reversed from the credit card. I called and the consultant could not assist me. This morning I emailed my private banker and his consultant and they cannot assist me. This service is pathetic as I have been struggling with Standard Bank for a change in debit order date for the past four months and they not getting this right.
