MTN CUSTOMER SERVICES OVER CHARGE AND POOR SERVICE.

On and about 13 May 2025 I had contact MTN Customer service regarding a cancelation of my wifi data contract. I was advised then not to cancel it but to down grade to 3 month reduced payment for minimum data. It was R49 for 10 gig data.on that day MTN sent me a debit check to confirm. It said R98. When the customer service consultant contacted me the same day as why I didn't accept the debit check, he advised that R98 was a figure to confirm the debit check and I would pay R49 a month. I have emailed MTN customer services over the past 2 months as I was charged R98 respectively for each month. The email was only to conform my details and banking details, I don't understand, there was no call back back from MTN customer services to assist. To me they clearly know what wrong they have done and are avoiding contacting as they know what they have done was wrong. The conversation with MTN Customer service was recorded regarding the change and the payment value. I don't understand why they are not resolving the matter.
