Vodacom upgrading contracts without customer concent

I have had a router contract with vodacom the contract expired and acording to the rules you then go over to month to month until you cancel. On the 29/9/2022 someone from vodacom phoned me to ask if i want to renew the contract i declined and told the lady if i want to upgrade i will do it by myself and i will go in desember to sort out my contract. Next day 30/9/2022 i recieved an sms saying that the contract was now extended to 2024 and well done on my upgrade this message can through after 19:00 so the call centre was already closed. I phoned today the 1/10/2022 there the consultant told me i can not reverse this contract. I kicked up a fuss and told her that if they do not sort this out i will definitely go to hello peter. She then put me through to her supervisor she said she will escalate the problem. Well after a whole day off waiting for them to sort it nothing has been done. Vodacom you better come up with a solution fast because i am seeing my lawyer on monday morning. You can not give someone a contract without there concent or approval. And you need to fire the employee who did this i want to see action very fast!!!!!!
