Missing funds

I made a payment of R800 to my African Bank Silver Credit Card from my Capitec account on 24/08/2020 and it is still not reflecting. I have made numerou phonecalls to the African Bank customer sevice to no avail. I sent them the proof of payment and I recieved a message saying: Hello Mr Jansen Van Rensburg. We are sorry we cannot complete your request because Payment cannot be found-refer to your bank for investigation for Account Reference/s ***. Your reference number is ***. If you have any questions feel free to call us on ***or visit your nearest branch. African Bank Auth. FSP Reg NCRCP7638 RDC91017/16. And while all this is going on more and more costs are accumulating on my account. Im sick of bad customer service.
