Cancellation Nightmare

I requested line cancellations in January 2024. This was not done correctly, and I had to request it again in February. Then, at the end of February, Vodacom converted my main just upgraded cellphone line to prepaid, something I did not request. I have been trying to get this fixed since the 29th but still have had no joy in getting this fixed. I am not getting any feedback from Vodacom at all.
