About a cellphone contract

<div>Good day I am doing a review on vodacom,they have terrible service and they are expensive. Im being charged R800 dor a payment that I was never notefied on they also took R110 rand from my account and there argument is that I did not have the amount of funds for payment but I did have more than enough fund for the payment

A guy from homemark resubmitted my contract from vodacom and told me I will only be paying R240 and now vodacom told me I will be paying R315 a month</div>
