Pathetic Customer Service from MTN ( ****mers)

I am totally disappointed and frustrated with MTN South Africa I too have problems, I took a cellphone on contract paid it well for about 8 months, they started double debiting my account which completely disturbed my monthly budget, I reported this to 3 of their stores, on all occasions I was told to send my bank statement to their accounts department which I did, I contacted their customer service line to try and get this resolved, however it was an epic fail,this was in 2022. I stopped paying my account because of the frustration, they'd double debit me but the amount on my MTN statement only reflected 1 amount instead of 2. Fast forward to 2024 I received and emailed that states my account had been handed over to Mbd attorneys, I paid money into the mentioned account information, I asked for a statement to show that have been paying my account since my credit record shows that no payment was received on my MTN account, I called Mbd attorneys to find out why the money I have been paying hasn't been allocated, I was then told that they no longer collect money on behalf of MTN, the account listed under the banking details on the email belonged to MTN. I reached out to MTN South Africa again to try and settle my account..Continuing from where I left off, this is a response I received from MTN South Africa, I called the aforementioned attorneys and I was told they do not have my account with them, I emailed them again, and I was told my matter has been escalated to their legal team and they'd get back to me within 48hours, guess what? It's been 10 days and no one has reached out. At this point I'm defeated by MTN South Africa pathetic service, I regret taking up a contract with them. My credit record is messed up all because of them. No one wants to allocate my payments nor remove the account from my records, at this point I feel hopeless that I'll ever get assistance with this regard.
