Bad service at MTN

MTN services are atrocious. Staff nor qualified or trained In December 2022 I ordered and received a wifi router on a contract after making sure the reception was good at my residence. Battled for quite a while to get it up and running until MTN admitted that there was so wifi signal at my home. Customer care advised me to return the device intact to the nearest shop (Waterstone Village Somerset West) they then filled out all the forms and told me all is well. Couple of months later there is a huge oustanding amount that I suddenly owe them. Apparently I was supposed to pay a cacellation fee and they would put a credit through wich I was not informed about. Many calls to customer care and being sent from pillar to post in the many different apartments they have each time to be told the matter has been resolved I started corresponding via email. Sent all the documentation they need and always get an automated reply apologising for the inconvenience and they are investigating the matter. So my services get suspended and the only way to fix the mess is to pay them R 3652.00. I cannot even cancell my contract before I pay the outstanding amount. Which also means I cannot port to another service provider. By their own admission it was their fault but no option other than paying. I have sent all relevant documentation to Customer care but more than two months later nobody can solve the issue It seems as if their customer care departments are not even communicating with each other Seeing as I have now paid that huge amount for no usage of the device and no hope of ever being refunded I feel I should at least get the router back and I could try to sell it. After all I paid for it! MTN will never see me again
