Disappointing, be careful of Vodacom adding charges/changing your contract without your approval!

We have 3 family contracts. Towards the end of last year, Vodacom added additional charged to all of these accounts, including insurance costs, game mine etc., without any approval.

This year I tried to change a contract for 1 of the phones. I was informed that I could only change upwards as the the phone contract had been renewed. I asked for the recording of the renewal, as we did not request an upgrade and can not recall renewing for 24 months. To date I am still waiting for them to come back to me. When I phone the call center, you either get transferred, and then curt off, or a message to say it is not available. I have also written to the customer care - but no response.
