MTN is SA Mafia

2 years ago, against all my instincts, I upgraded over the phone with MTN (Summer Mobile) I upgraded 4 contracts, one of them being a new device to which was added a booster bundle. The Phone did not arrive and after many months of paying for the phone without having it I managed to cancel the contract and upgrading instore, but unbeknown to me the booster bundle was not cancelled. 24 months later (Feb 2021) I want to cancel 2 of the data contracts and the booster bundle. At the beginning of Feb 2021 I cancelled these contracts on the phone and was assured that they have been cancelled. During the month I called a further 2 times and was informed that the contracts show on the system as being in the process of being cancelled. I now received a new invoice for all 4 contracts for a new month including the booster bundle. I called MTN to query this and was told that there is no evidence on the system that these contracts have been canceled. I have also sent emails to cancel the contracts , but nothing is being done. This company is a mafia organization that does not work to normal business standards. I have spent hours on the phone trying to achieve simple things without success. I have been to an MTN store to cancel the contracts but they have to phone it in to get it done and you stand in the store for hours but get nothing done either. what do I do now. I have been told that this forum is the precursor to going to the ombud for cellphones, so this is why I am making an official complaint here. Stay clear off these ******. I would have given the minus 5 but one star is the worst here and trust me this is really highly over rating them for service.
