Disgusting MTN opening *****ulent contracts and then failing to address their mistakes

November 2024 we were called from MTN with a few options to upgrade. our contracts were at that stage on a month to month. we opted to upgrade one contract and cancel one contract. however what MTN did was to upgrade both existing contracts and open two new additional contracts on top of the existing ones. over the last 4 months we have managed to cancel the two additional contracts and the 1 that was supposed to be cancelled originally is still giving us a problem to cancel..... on 16 January 2025 a credit R1172.64 was passed and an email sent to us confirming such. from 16 Jan 2025 to date the credit that was passed as still not been allocated into the account. our account still shows an owing balance of that credit amount and now MTN decides to cut our lines as we "have an outstanding balance". MTN customer care keeps transferring us from one department to another or they simply just cut the call or tell us the department is closed and we should call back the next day only to be given the run around again. we are so tired of this now. MTN needs to sort out their mess before forcing out money which is not due to them.
