Disgusting customer service

I have been with vodacom for +- 6 years. I took out a LTE contract with vodacom on the 23rd of March 2020. I have had issues with my network since then. Network issues and so called issues being escalated to their solutions experts to fix the matter, it still has not been fixed. On the 3rd of August 2020, I received a called from their network team saying that my issue with the network cannot be fixed and that he will send a request for contract cancellation on this basis and that I would not need to pay the remainder of the months for early cancellation. Mind you that this bill works out close to R20000 and that money I don't have. I have been back and forth since the request have been put in, been given the runaround for weeks now. I received an sms last night at 18:54 stating that my number has been moved to a prepaid and that if I have any queries, please call Cancellations on ***. I attempted to call, my number has been blocked from calling this department. all I wanted to know is what the bill would be for me to pay. Please stay away from vodacom. Their service is disgusting and treatment of customer does not live up to their status.
