MTN shady business practices

I have been trying to get my service reactivated on mtn since Jan 2022 and I have spoken to various call centre and collections people on 31 occasions since then. They all gave me the amount to pay which i settled in full. On the 19th I settled the full outstanding amount and after calling them once again I was informed that they had cancelled the contract and that I need to pay the cancellation and device fee. I then requested to speak to the manager who informed me the same but said that he would escalate and send me the ticket number as well as a form to request the calls and a list of people I spoke to. This.of course never happened and no comms were received. No notification of the cancelation was given and I was in constant contact with MTN. This is now impacting my livelihood due to *********** staff and the fact that MTN simply does not care. i need my service activated asap!!
