Vodacom cannot be trusted

So I received a call from vodacoms upgrades department on the 23rd October to have my line upgraded. For some reason the device I wanted was not within my reach. I advised the consultant that they may leave the entire thing alone. Without knowing the they upgraded my lkne without consent. Breaking my consumer right and not allowing me to choose what benefits suits me. Since the 25th October I called Vodacom everyday to follow up on why this happened and they need to cancel this request but I have been given the run around with no resolution. People don't trust Vodacom as they lie to their client and Rob them to suit their profit margin. #unhappy client still waiting on a resolution.
