Billing Discrepancy and Unauthorized Deduction

I have been a loyal MTN customer for over four years. On 27 September, I made my usual monthly installment payment. However, I was shocked to discover that an additional R927.00 was deducted from my account without prior notice or authorization.

Upon contacting an MTN store assistant telephonically, I was informed that the deduction was due to “underpayments” over the past few years,allegedly because I had been paying slightly less than the actual monthly amount due.

This explanation is unacceptable for the following reasons:

Every month, I request the outstanding balance and pay exactly the amount communicated to me by MTN staff.

If there was any shortfall, why was I not informed for the past four years?

A sudden, unapproved deduction of nearly R1,000 is financially disruptive and unjustified, especially when MTN has been in control of the payment information provided to me.

I am requesting the immediate reimbur*****t of the R927.00 and a detailed breakdown of my payment history showing how this amount was calculated.
