MTN *********** customers

On the 6th of August 2024 I bought month on month MTN home router contact online. Upon completion of the application I was prompt to pay for the router so it can be delivered which is prorated for Aug and full pay for September. I paid R494 using my bank card, and 2 days later I received my order. The problem started when MTN attempted to debit my account on the 13th of August of the same R4944 which it was unsuccessful AND MTN charged R11 for failed transaction. I called MTN and was advised that I am owing. Few days later I called again and was told that the debit order was incorrect the online payment is reflecting and the R11 charged will be credited to my account which they did. 2nd September I received a reminder to be debited R477, and when I called I was advised that I am owing the payment was not received (online payment for the 6th August). I've spoken to different MTN consultants who tells different stories each time. MTN is ripping people with their online purchase. Today I am debited that R477
