MTN Cancellations Department Does not Answer the Phone!!

I am very unhappy with the painful process of closing off a matured contract between myself and MTN. I paid my last installment on the 20th of April 2021. I have called the cancellation department on three different occasions in order to ensure that I am not debited in May. Especially since I received an sms stating that my month to month payment on the contract would be more than R1200- I was paying about R239 for my data contract.

The appalling part is that 1) I cannot cancel the contract from an MTN store, 2) I have been on hold waiting for the cancellation department to answer for more than an hour and 3) when I enquired at an MTN for assistance it was imp**** that I was not patient enough. Furthermore, I was told that I need to keep holding for as long as it takes.
