Done struggling to get prepaid

I want to cancel both of my contracts and go on prepaid as I don't want to loose the numbers. The reason why I want to do this is because we don't have cell reception on our farm and is paying a lot of money every month, esspecialy during lockdown.

I first contacted them on 29 June 2020. The lady logged a service request for an IT-technician to come out and see if something could be done about the reception as we are actually receiving service from MTN. Secondly she offered me a new package for R83 p.m. on both numbers and told me I had 14 days to think about this package. I didn't really want a new package, but took it as it was a relief on my financial state.

I called them again on the 14th day (13 July 2020). I spoke to Precious. I said I want to cancel this new package and go on prepaid. They had 14 days to attend to our service request and didn't so now I would like to go back to what I originally wanted on 29th of June. She kept telling me that she can't do this for me and told me not to raise my voice at her when I told her that I am the customer and I want to reverse this package and go on prepaid. She again logged a service request for an IT-technician as she can't do anything for me without a reference number from the technician...

I called again today (4 Aug. 2020) and spoke to Amos. He was very nice. He actually reversed that package, but now I have to wait until the end of the month to apply for a cancelation. This really is unacceptable. I just want to go on prepaid. I feel that I am just going to go through all of this AGAIN on the 31st of August.
