MTN ACC's DEPARTMENT AND THE APP SUCKS BIG TIME - NOT TO MENTION THE KNOWLEDGE OF CONSULTANTS

MTN ACCOUNTS DEPARTMENT AND THE APP SUCKS BIG TIME - NOT TO MENTION THE KNOWLEDGE OF CONSULTANTS. I got Married in September 2021 and changed Banks in early October 2021. I logged into the APP, and changed my marital status as well as my bank details so my next debit order could go off new account. When debit order was suppose to go off it did not. I got a message saying debit was unsuccessful and my line suspended. I called and made an arrangement. But MTN the Glen could not process my payment. So my mom helped me to make payment from bank app into MTN's bank account being:- ABSA - ACC *** - BRANCH 632005 to the amount of R210.51 via EFT on the 6th of Nov 2021. Bank Trace *** - ACCOUNT ***. On 9th Nov 2021 the money was returned into my bank account with a *** UNP 26.... NOT SURE WHY AND WHAT IT MEANS. SINCE THEN MTN IS VERY DIFFICULT TO CONTACT AS THEY DO NOT READ THEIR EMAILS PROPERLY SO THEY RESPOND to things not concerning the problem. Today I called again and was told they cannot make an arrangement. Again this woman doesn't listen or do not understand what I am trying to say. If asked why was it returned four days later when account details etc. was ok, and can I try do EFT again, submit proof of payment again and you restore line ? She said no they cannot make another arrangement. Now really, how do you solve a problem like this when people cannot think for themselves ?
