Vodacom - Data

<p>This morning i loaded 250mb for R59 i went to facebookand twitter and scrolled down, just after that i received a message saying o had an x ammount of data left, whilste i read the message another message came through rhat said i had run out of data, keep in mind whilst i was reading my messages my facebook and twitter was closed even on the background. I then proceede to load a just 4 you bundle of 200mb for a day, i went on the internet to search something, the page didn't even load and i received the sms again saying low data what i going on? Why is VODACOM *****ing my data and money? I want someone from vodacom to contact me asap cause this is unacceptable. </p>
