POOR Capitec Business Banking customer service

On the morning of 2 November 2023 I made a payment from my Capitec business account (which processed successfully) and requested a Proof of Payment to be sent along with it. Today is the 6th November and I still have not received the POP, even after the NUMEROUS calls I have made since the 2nd November- which means I cannot send POP to my supplier, which means my business is being held up! On the day of payment I called the call centre and I was promised to have the POP either end of business that day OR the following morning (which would be 3rd November). Since then I have been calling, have gone through 3 call centre agents, and I'm constantly given some muddled story no matter my stressing the urgency of this POP. IT'S UNACCEPTABLE TO HAVE MY BUSINESS DELAYED BY A PROOF OF PAYMENT, which I should be able to simply download off my banking app! I DON'T EVEN WANT TO GET INTO THE BANKING APP story- a disaster! I hope now I will have someone's attention after blasting this bank on Hellopeter. PLEASE can I get the POP email.
