UnHappy and dissatisfied client

<p>I have been charged extra charges for my 5GB Internet account with vodacom for the last 2 months. I do not make use of my wi-fi Internet to surpass the 5GB I have available. Usually there is left over from previous the month. Last year November vodacom also charged me with extra but after investigations they gave me a Good will gesture and decreased the amount. I am very careful with my Internet usage and also use rather the Night Owl after midnight instead. I have contacted vodacom with no reply to my query regarding the last two months bills. Last year I updated my contact from 3GB to 5GB to avoid over usage but I am still being charged for extra usage which is not happening. My smartphone also shows the amount used on wi-fi and it's far less than 5GB. I think vodacom is robbing us as they also have no proof of our usage.</p>
