MTN early termination process is terrible

Requested an early termination of a post-paid contract late in December 2021, with the expectation that the contract will be cancelled by end of January 2022. Logged the request via all the available channels (e-mail, customer support, etc) only to discover despite confirmation and reference numbers that nothing has been actioned and yet another month's fees will be incurred. The call center experience was terrible - transferred between 4 MTN consultants and hanging on for more than 24.5 minutes at a time for this simple request. E-mail response turnaround is 16 days. I had to pay the additional amount for early termination at a physical branch, despite having a debit order and none of the account numbers provided by MTN works for EFT. I'm not even clear if the account will be closed by end of February 2022.
