MTN Cancellations are Pathetic!!

I have been trying to cancel (move to prepaid) my contract since EARLY DECEMBER I have 4 numbers, of which 3 were required to be canceled. I went into the store and they said retentions will call me, which they never did. I called in Mid-December, to which the request to move to prepaid was apparently approved. In doing so, I was charged an R150 cancellation fee (why?! The 2-year period was fulfilled) In January, I attempted to port my number to another service provider, and to my surprise, the numbers that I tried to move to prepaid were not moved successfully. Again, I go into the store on 02/02/22 and they were not able to assist. I called retentions again and they said that the numbers were zero-rated (not as per my request) and they will call me in 24 hours to confirm that the numbers were moved onto prepaid. Again, no call was received. I call on 07/02/22 and the very rude call agent says that I will have to wait another 30 days for the number to move on to prepaid and there is nothing more that they can do?! The entire process has been horrific and I will certainly not be returning to MTN after 10 years of loyalty.
