Bad mtn service regarding payment

I refer to my review on 1 March 2024 regarding payment of my account wbich was unsuccessful by debit order. I was informed that a new debit order was created for payment on 1 March 2024. I visted Mtn jzkaranda and was informed and assured that the bedit order was successful. The guy at the store showed me paypent was made on their computer. But nothing showed on my bank side. Once again i went to mtn to get proof of payment. Went back to bank and after an investigation nothing was on their system about payment. Today i received a notification my account was not paid. What a total mess up. Not acceptable.
