MTN Failing to Process Debit Order Despite Multiple Requests

I am extremely frustrated with the poor service I have received from MTN regarding my account payments. I have now set up my debit order on two separate occasions, ensuring that all the required information was provided correctly. Despite this, MTN has still failed to deduct the monthly amount from my bank account. The most concerning part is that the funds have been available in my account, and I have done everything within my power to ensure the debit order is active and able to process successfully. Yet the payment is still reflecting as missed even though I manually made payment which could negatively impact my credit profile through no fault of my own. As a customer, I should not have to repeatedly follow up on an issue that has already been addressed multiple times. MTN's failure to process the debit order correctly is causing unnecessary stress and inconvenience. I request that MTN urgently investigate why the debit order is not being processed, correct any missed payment records that resulted from this error, and confirm in writing that my account and credit record will not be negatively affected due to MTN's administrative failure. I expect this matter to be resolved as a matter of urgency.
