Vodacom Data Charges by Ripping Customers Off

So I wrote a review about getting a call from Vodacom to telling me that they have been ripping people off on data, so have been losing customers. Going thru all the reviews of Vodacom it is amazing that there are tens of thousands of people complaining about the same thing. A consultant phoned me and said she would investigate as I had 2 separate complaints about Vodacom phoning me & offering me wonderful deals but they force you to sign a 24 contract which is great. I then ask how much it would cost to upgrade my phone & was told they cannot offer me the phone I want. So now I still have to pay the exorbitant rates I am currently paying because Vodacom can't offer me the phone on that contract. I can upgrade by signing a 24 month contract but then cannot add the phone at a later stage either. The consultant phoned me two weeks ago and was going to come back to me & still has not. My review is then marked as responded telling me that I must buy additional data at cheaper rates but still have not actually resolved any of my complaints. As a customer of Vodacom for over 18 years, Vodacom doesn't reward you for being loyal & I can get a much better deal with a new contract with a new Provider. Vodacom will lose my business & hope more people follow.
