Mtn is ******** Long Standing Customers

I am an MTN customer and have been for more than a decade. I have a contract that ended in January 2022 and changed to a month to month.

I’ve been receiving calls from third party sales companies in the past 12 months on behalf of MTN to get me to upgrade but I didn’t need to.

On the 20th of January 2023, I received a call from the Mtn retention department to offer me a package that reduced my monthly payments to R179 pm and I’d get over 500 minutes and 17 gigs of data. I took this “great” deal.

On the 24th of January 2023, I get a debit order mandate request on my bank account of R8500 from Mtn.

I’ve been trying to sort this out through all of their channels but it appears they have no interest in assisting a long standing customer.
