Unprofessional, *********** and worse service ever by MTN South Africa

I have a cell phone contract with MTN and since 03 March 2020 Have been Contacting MTN regarding my account as I wanted to settle the remaining balance on my contract and MTN consultants told me that my account has been handed over to Norton Lambrianos attorneys, to my surprise when I call Norton Lambrianos Attorney's they tell me that the account was never handed over to them and its not even on their system. I contacted MTN to tell them that Norton Lambrianos Attorney's noted that they account is not with them. One of the unprofessional MTN consultants told me that the is nothing they can do as on their system it shows that the account is with Norton. Like what kind of a sick game is this...Currently I cannot settle my account because basically MTN lost my account. The MTN consultant told me that I can no longer make payments with MTN because the payment won't be allocated as the account reflects that it is handed over to Norton Lambrianos Attorney's but Norton is refusing to say the don't have the account with them. Look This is affecting my Credit score in the process and I lost out on a Job opportunity because MTN refused to give me a letter stipulating that I am paying the account...they today me the letter can be issued by Norton Lambrianos Attorney's of which Norton said they don't have my account with them. This is very tiring process because I just want to settle my contract. To MTN I suggest that you close my account up until the matter is resolved because you basically lost my account and interest keeps on pilling up on an account that I can not pay due to your Incompetence and negligence.I advise anyone who wants to take a cell phone contract with MTN rather go for other service providers as MTN provides an unprofessional b***sht service.
