MTN and false hopes

Dear MTN. As a valued customer for 15+ years I have uncounted some wild affairs with my various contracts but this one takes the cake. My usual debit order has gone off yesterday 27/08/2024 but with an extra R2023.87 been deducted. Now, in this day and age like most South Africans I cannot afford this mistake to happen. So I call into MTN in which the consultant refers me to the ***** department REF -***. The ***** department refers me back to the billing department REF - ***. The consultant advises me that he has logged a call, removed the extra add on which I did NOT approve on my account and informs me that it will take 24 hours and the money will reflect back into my account. 24 hours has gone by and no transfer has been done. I call MTN again today REF *** and the consultant has informed me that the ticket is still open, with no notes on it and it will take up to 7-14 days before the money is returned. Now here is my problem, I have debit orders that has gone off and returned due to insufficient funds. This will result in bank charges been done and a negative reflect on my credit score as the bank will return my debit order as insufficient funds. I asked the consultant yesterday who added this unwanted service to my account, he should be able to see the notes on your citrix system and he could not answer me. Now tell me MTN what are you going to do about this and why am I the one that is suffering. I need the money back in my account ASAP and are you going to compensate me on the bank charges? Also as per the consultant the extra charges on my account amounts to R1090.00 but you deducted 2023.87 more than you are supposed to. I need answers TODAY
