MTN has Terrible Client servicing and call centre agents

Mid June i upgraded 2 * Data contracts on my contact. The consultant ended update upgrading a cell number that i do not have on my contract and it’s not available to me. I was told that i cannot cancel but i should try a sim swap. I then paid an additional amount for the sim swap but that did not work. After many calls with terrible client servicing i am at a loss. As i am told by each space there is nothing, they can do for me. For the second upgrade done, I just received an email saying that this contract option is no longer available and that are upgrading me to a higher contract, How is this even allowed. Question: How can a consultant upgrade a number that i don’t have, as it is not one of my contract. How is it that nothing can be done to rectify. I was happy to continue the contract, but it needs to be on a number that i have access to, is that so difficult to understand. Consumers really have no rights anymore; these big corporates just do as they please and don’t know how to take accountability. If I did not need the data service, I would be so happy to never use these service providers, but they know we need them. I would really like someone competent to speak too, as MTN consultants cannot help with online upgrades as it done by the 3rd party and the 3rd party says they cannot help either.
