VERY POOR CUSTOMER SERVICE!!!

Customer service is SUPER poor!! My contract expired on 1 May2022. I want to go on to prepaid as I no longer want a contract. I went to an MTN branch who advised that I need to phone the call centre to get the cancellation done. I phoned the call centre on 6 May, who assisted with the cancellation. My phone then went off the next day. I managed to phone the call centre again and they advised that I would need to RICA, which I wasn't informed about when doing the cancellation. I then did the RICA and was told that the RICA has already been done on this number. I phoned the call centre again on 7 May and they advised that it takes 2-24 hours for the cancellation to go through and my phone will not be active until such time when I can then RICA and it will then work, but I can speak to the cancellations department to escalate and they can get it done quicker. I was put through to the cancellations dept and the main call centre answered and advised that the cancellations dept is closed and the cancellation will only happened on Monday!! Not happy, but ok. Waited till Monday, phoned the call centre AGAIN and they advised that the cancellation has gone through and I can RICA now. Went to RICA and was told again that the RICA has already been done. Phoned the call centre AGAIN and couldn't get through and got cut-off when I did eventually get through. It is now 11 May and the problem is still not sorted!! Phoned the call centre, held on for 9 minutes. Was then cut-off. Called again and consultant advised that it takes up to 20 days for the cancellation to go through and my phone will not work until then!!! I was not advised of this when doing the initial cancellation... This needs to get resolved ASAP as it is utterly ridiculous that I firstly, wasn't informed about the process, secondly, am being given a different answer from every different consultant and that my number is STILL not working almost a week later!!!
