Vat issue on Vodacom Contracts & 5% average price increased a **** as reality its 11%

Worse nightmare on contracts with Vodacom - sales call center agent quotes you contract prices & customer verify that they are inclusive of vat - come billing time they add vat on what was quoted to inflate charges to customers. next they announce a price increase on newspapers of 4.5% average , Customer verify & call center verify this increase on call at 5% fixed on the call & boom Vodacom billing doubles the increment to 11% on your contract saying its the plan increment, how so as me the customer never agreed to 11% increments that is not even near inflation. Worse night mare telecoms scandalous company. I agreed on prices over the phone & need to be charged those agreed amounts not what Vodacom wishes to charge & rob customers for their greed. I was cancelling all the contracts with Vodacom only to be given unreasonable & 2 ****mer deals disguised as price increments with 11% increments. What I agreed on call with the agent is exactly what i will pay Vodacom.
