bad service

<p>I was on the internet for about 1hr but after using the internet i checked my balance and vodacom charged me R1504,29 for being in the internet for about an hour and when i started to use the internet i had 500mgs, i called vodacom to investigate on this matter since 2019/10/03 but till 2016/11/12 they still cant tell me how can i be charged that huge amount, even though i did not do any downloads. i have been calling vodacom since the begining of november but no one can tell me how can i be charged that huge money for data.</p>
