Vodacom is Pathetic

So I have recently changed my Vodacom pacadge to a cheaper solution due to the economic uncer*****y and my current contract running on a month to month basis (original contract expired end 2020) When I called to implement the new transaction I was firtly wrongfully advised on the new deal I made with Vodacom. The day after another consultant phoned me to explain that I was wronfully advised and corrected the deal (which is also pathetic) costing me more than what was sold the day before... Hereafter I was billed aproxomately R 6800 for changing the contract (which has exprired) and was never mentioned to me. I called Vodacom to dispute the amount whereafter they told me they will get back to me, which they have also not done. To date I do not even know what the status of my contract is and if everything is in place. I expresidly asked for the recording to confirm my case and Vodacom said they will investigate and get back to me. I have since heard nothing and they sit with my money in a time that I desperately need it with no urgency on their side. You also never seem to get through to them as it takes about an hour te get through to speak to any consultant. My referance number is ***
