Cell C system migrate me automatically without my consent.

Hi, on 25th of Sept 2020 i got a weird sms from Cell C saying that my migration has been approved. I phone them saying that i did not ask or permit a migration. The lady said i was not the only person with that got a sms like that and that its a technical glitch on their side. I DO NOT HAVE TO WORRY. Cell C will sort it out. Then on the 1st of Nov i did not get my benefit (Voice, data and sms). I phoned again and was told yet again they are experiencing system glitches and it should be sorted shortly. I got a sms saying that the line manager will contact me shortly and that i am one of many who did not get their benefits. 5 hours later i phone again as nobody contacted me. Again i was told the same story. On monday (2 nov) i phoned again and was then told that i did not pay my account. Cell C migrated me to a Forward paying package (Hybrid Zero) and that is why i did not get my benefits. since the start of being with Cell C my debit order always went of on the 28th of the month. The person on the call centre said i should go into my nearest shop and they will sort the problem out for me quickly. 2 and a half hours later and many many phone calls.......NOTHING. the staff at Dainfern Mall was fantastic in trying to help me but we got send from pillar to post and back. I have done nothing wrong in this whole thing but i have not had any data or voice on my phone. i use it for work. i had to take the day of work yesterday to attend to this problem that is still not solved. it seems nobody in Cell C has the know how in how to fix this problem the they created. i was given the option of migrating from the Hybrid package back to my old package but then i would receive half the benefits and have to pay more money. i declined. They have escalate my case now, but i was told this on sunday as well and nothing happened.
