Billing Errors not corrected

Hi,

I have been a loyal MTN customer for over 10 years. I have never had any issues with the service provided to me. In December 2020, a data contract was upgraded on my account. The data sim contract is R299 per month. I received my invoice on the 19th of January for an amount of R1129 to be deducted off my account in February for the data contract. I called the 135 service, and explained that the invoiced amount is incorrect. The billing department advised that this will be resolved, and credited. I thought this was the end of this issue.

I received my new invoice on the 23rd of February, with the original invoice that was reflected in January. I called 135, and all they can do is say that I will be credited for the following month. This was over a month, and yet MTN has not been able to update the invoice to reflect the correct amount.

Ticket number : *** is the latest information as of the 24th of Feb 2021.

Can anyone help?
