Telkom Billing and poor customer service

This is a month to month issue I experience since I’ve had my phone in November 2021. I’ve opted for debit orders to go off the 25th of every month and this has not been happening. I’ve been to Telkom stores, called the call centre on numerous occasions. A call was apparently logged on my behalf and this was ‘resolved’ but come today, I’m being told the same reason I was told before the call being logged. I am told the debit has been cancelled. I’ve been to the bank and not even once has Telkom initiated a debit order. How can one urgently resolve this as it is causing an inconvenience for me and affecting my credit score!
