Vodacom poor customer service

It has been almost a month of trying to get vodacom to correct my account and give me a reimbur*****t after them changing my account without my consent and being over billed by +- R1400.00 and my account is going to be incorrectly billed again end of September due to them not doing anything. Short version of my process so far is that I called 30/08/2024 was told 24 to 48 working hours. Emailed 06/09/2024 and got no response.Tried the Vodapay app on the 10/09/2024 and was directed to the initial number I called. Called again 10/09/2024 and was told nothing was done on the 30th and a service ticket (***) is logged and i would get a call back which never happened. I called again 12/09/2024 and was told they can't do anything as it's still being investigation and would be called back. Recieved call 17/09/2024 back to find out if it had been resolved but nothing was done and i was told that they would look into it again and call me back and nothing has happened since again. Everytime you call to follow up you get a diffrent person who knows nothing and you need to explain everything from scratch and no one keeps to deadlines and nothing actually gets done with your issues.
