Furious Over-Charged Client

Vodacom has charged R1700.00 for 'Vodafone Live' on top of the contract value R328.50/month Smart-S cell contract. What's Vodafone Live? It was never part of the contract I signed for - I've never subscribed to it. I regard this as theft of the highest degree. I've been to the Vodacom store 4x now since start of April. Emails have been sent to Vodacom accounts by the consultant. The entries have been marked for credit, but 4 months later I'm still waiting for the 1st credit. In spite of accumulated air time I now get charged R575.84 for Entertainment Services in place of the Vodafone Live. Vodacom this is ******ion!!
