Failed as network provider

Cell c has put me through a financial inconvenience. They have failed to debit my account on the due date. I had to chase them up to make a payment. I finally made the payment on the 04/01/2022 and till date they have failed to update the records. Now I have to take time out work to run and chase after a damn proof of payment. Why can't an sms and bank statement be enough. You as a network provider is disgusting!!!!! Called customer services which was of no help. The service I have received is appalling and absolutely disgusting!!!!
