MTN complaint: debit order wrongfully loadeddeducted

Good day, I am pleading to find a solution. Between contacting the call centre and the Meyerton store it seems that there is a discrepancy and the system is not the same at MTN headoffice and the MTN stores. I went to the MTN meyrton franchise last year FebruaryMarch to change my debit order details because I got a new bank account. The lady at the store helped me with this and I filled out paperwork. Much to to my shock in October my account was suspended. I didnt get any communication to state that my debit orders were unsuccesfull. My account was susppended and I had to pay the outsanding amount. Juanita at the meyerton store ed that the system on her side shows I am a cash paying customer, (please also see photo attached) hence I paid in store or via the app since then. I got a sms 2 weeks ago stating my debit order was unsuccessful. Again MTN is taking a debit order from a closed bank account. I called the centre this morning and the lady that helped me was very unhelpfull – she said hetr system shows I have always been a debit order customer, If the lady at meyerton said I am I cash paying cutomer I should sort it out with her. This response is not very helpfull. I also had to hear about MTN budgets! and this I fully believe has got nothing to do with me – MTN should sort out their internal matters. There is a system error on MTN side. I as the customer are stuck in between and the bad thing is my credit score is being affected by this – wrongfully and I am being panalized with the unsuccessfull debit order- why should the penalty fee be for my account? I don’t know who to believe? and what to do?
