MTN is ****ming me!!!!

MTN is a ****!! Words can not begin to describe how livid I am but I am tired of being ****** by them!!!! My Husband and I have been having a problem with them and our Wi-Fi for the past 4 years. Our contract expired and we decided to continue to pay month to month for both our home and business Wi-Fi. For some reason the network became horrible and I decided it’s time to switch to a better network provider. Since we’ve decided to pay month to month they would immediately put the Wi-Fi off until we would visit an MTN store to pay, however they decided to not put it off- I’m not sure if I the customer was supposed to go in store and tell them to not keep our Wi-Fi on because we haven’t paid and don’t plan to at all !!! I am now being told I owe over R6k and have to pay an additional fee to terminate the contract!! This is not the first time MTN ****ming us. In 2022 we bought and paid for home Wi-Fi which till this day doesn’t work!!! It is not my responsibility to teach MTN employees how month to month payment works. It is not my responsibility as a client to go into store and put my Wi-Fi off!!! Why not put it off the way they usually did when it was time to pay again ????
