MTN USELESS

After numerous store visitors, emails and phone calls I am not closer to having my problem sorted out. In May I was contacted by Ignition group ( they handle Mtn contracts) for a upgrade on my contract but the Monday I saw it wasn't going to work for me and I canceled the contract. Which was within the 7 day cooling off period. I was told it would be done. A month or 2 later I wanted to take out a new contract but was told I already had n new contact to 2023 but informed them. That I canceled it. I was told to sort it out with ignition group which I have been trying to for the passed few months. They then told me at the time they had a problem with there computers and the cancelation was not processed but has it been done since then no it has not. I have now been trying to get it resolved with MTN and I got a message saying that the reversal in not applicable as the current contract is older than the allowed no of days. But I followed the correct procalls the mistake is on there side. But they can't rectify it. And I can't change my contract because of there incompetace.
