Unhappy Customer

I had a very bad experience with MTN and this is going on for a while, My salary date changed from the 1st to the 3rd of each month and requested debit order change on 15/05/2020. I got a email confirmation that it was changed, the 1/06/2020 i was debited and accumulated charges, i then get an apology to say they cant deduct on the 3rd as their system can't allow them. i requested that they stop the debit order will do EFT of which m doing ever since. Their response "Good day Mmanoko,

We apologies for the inconvenience on the incorrect response. Your request to change from debit order to cash payment method has been sent to the supervisor for processing.

Please accept our sincere apology for the delayed response.

Kind Regards, Magaret Shongwe MTN SA

Reference Number: ***" I am still awaiting the supervisor to cancel my debit order even today, I've tried to stop with the bank but they keep on changing the amount of which i don't understand why as we never agreed on that amount. I still get charged an overdraft fee each month and unpaid debit order amount since June till today for MTN. i really disappointed in MTN
