MTN - Mtn sa poor customer service

MTN Service is very poor, Please be advised that on the 27th of October 2022, I made an immediate payment for the 12th of October 2022 invoice and sent the proof payment on the same day. The next day, on October 28, 2022, I received an email from customer service informing me that MTN had received my payment. On November 7, 2022, my MTN simcard was turned off, and I was unable to make any outgoing calls or use data. I also had appointments that day and was running late. When I called customer service, they informed me that I had fallen behind on my payments. I had to resend the proof of payment on November 7, 2022 in order for my simcards to be activated. I have sent the email complain on the 21st of November 2022 to explain why my invoice shows R 2,930.90? instead of R1,461.24. On the 30th I receive a email from Portia at Complaints Management Team she said “Please note the balance reflecting on our side is R1,461.25”. On December 8, 2022, my MTN simcard was turned off again. When I call customer service today they told me that I still have outstanding balance R 1,461.25. I don’t understand why because it was confrim by customer service servral time and complaint management team on the attached emails that they received my payment of the 27th October 2022. Now the customer service says I must do payment arrangement in order for them unsuspended my service. Why should I do payment arrangement if I paid already.
I have ask the customer service call centre agent provide me with her manager’s email or transfer the call to the manager she said “she doesn’t have manager”. Please be advised that I am no longer able to use my phone; I am unable to make calls or access the internet as if it is my fault because the line has been suspended, and I have called customer service again; they are unfriendly. They simply put me on hold without informing you, and they even sang to me while I waited for assistance.

My four MTN simcards would not be activated until tomorrow, I was told. Since this morning, December 8, 2022, my MTN simcard has been turned off.
