Billing blunders

Every month, for years, MTN has been collecting my monthly payments via Debit Order, on the 1st of every month or, if the 1st if on a public holiday, on the very next business day thereafter. On the 01/11/2023, I noticed that MTN has not collected the payment. On the 03/11/2023, I called '135' to query this. After the "Service Champion" investigated, no explanation for this blunder could be given but I was assured that the payment would be collected within the next 4 hours. An SMS was received: '𝒀𝒐𝒖𝒓 𝑱𝑨𝑩 𝑷𝒂𝒚𝒎𝒆𝒏𝒕 𝑺𝒆𝒓𝒗𝒊𝒄𝒆 𝑹𝒆𝒒𝒖𝒆𝒔𝒕 𝒘𝒊𝒕𝒉 𝒓𝒆𝒇𝒆𝒓𝒆𝒏𝒄𝒆 𝑵𝒖𝒎𝒃𝒆𝒓 ***, 𝒇𝒐𝒓 𝑷𝒂𝒚𝒎𝒆𝒏𝒕 𝑨𝒎𝒐𝒖𝒏𝒕 𝑹𝒙𝒙𝒙𝒙,61 𝒊𝒔 𝑪𝒓𝒆𝒂𝒕𝒆𝒅 𝒇𝒐𝒓 𝑷𝒂𝒚𝒎𝒆𝒏𝒕 𝑫𝒂𝒕𝒆 11/03/2023.......' Well, today is the 06/11/2023 and you have still not collected the payment. If you dare suspend my service and charge me a re-connection fee, I WILL take this matter further. Are we clear?
