Vodacom fibre support agents are ***********

I installed fibre in my home through Vodacom door to door sales rep. The rep told me I will pay R199 for the fibre, when the January bill came I had to pay R1000. When I called Vodacom support I was told the R1000 is for pro rata and administrative fees which I was not informed about when I signed up. The same day I cancelled the contract, I called Vodacom again in February the agent could see my cancellation and explained that it takes a while until the fibre stops working, All calls had reference numbers. On the 3rd March I called Vodacom to ask for proof of cancellation, the agent tells me my contract is not cancelled and he cant see any of my references. When I asked the agent to go through the voice recording I was told there are no voice recording under my phone number. I was ropped by Vodacom door to door agent and now Im ropped by the Vodacom call centre agent who are ***********.
