Disappointed with MTN Customer Care

I have been a loyal MTN customer for about 5years.i made it a priority to keep my contract up to date.the problem came year end 2017 when my contract ended and I decided to cancel the contract.i did call the call center as procedure to proceed with the cancelation,but unfortunately the person I spoke to through the phone didn't made it easier for me to do the cancellation .she dragged the process and try to convince me to take another contract,we spoke for queite a while till I finally gave in and took the other contract but she promised me that anytime I can cancel the contract at a fee of R200 .so I continue with the new contract till September 2018 and I decided to cancel the contract due to fanicial challenges.so I call the call center and they told me another story,the said I am not able to cancel the contract as promised but I should pay around R900 cancellation fee.i explained to them the whole story that I only took the contract because I was promised that I can cancel it at any time with the cancellation fee of R200 and they said the should listen to the conversation which they recorded when they were selling the contract to me.they did that and came back to me saying they we sorry because the person sold the contract to me left out some important ifomation .she forgate to tell me all the terms and conditions.so I stopped paying the contract because my financies wouldn't allow me .but then March 2019 I decided to pay up my arreas with them so that I will settle my debt.i went to MTN store and pay up and they told me to call the Contract department so that they can activate my SIM Card again.i did that and they said my issue was send to their legal department and I should wait for 5 working days and do the follow up.they gave me a reference number 1-***7.i called them after 5days and no one could gave me a straight answer till I requested to speak to the manager.but the agent wouldn't allow me to speak to the manager but she **** to me and say their manager said my SIM will work within 24 hours and I requested for a reference number and she gave me 278 342 966.and it seam as a fack ref.so on Monday I called them again a requested to speak to the manager and finally I spoke to someone and she said to me I must wait for more 7 working days .so I dont know what does that mean ,should I just wait in the dark not knowing what's happening.i asked her if she can give me their legal department number but she refused.
