MTN INCOMPETENCY

I have been having an issue since November 2020. I upgraded my Black Friday MTN deal for a new R299 a month deal. Somehow, things malfunctioned on the MTN system, and I have been getting debited nothing less that R2000 a month. In fact, my last amount debited was R2832.76. I have to go to the bank to reverse this amount and then pay cash at an MTN store. Besides inconveniencing me, I have other debit orders that are going unpaid and incurring bank charges all due to MTN's incompetency. The matter has been handed to Faiza Kader who is afraid to speak to the customers and cannot resolve this. I would like to cancel this contract at no additional charge, but there again, MTN is unable to do so. I am extremely disappointed with the service from MTN, and i have been a loyal MTN customer for as long as I can remember. I would actually like to give MTN 0 stars intead of 1.
