Airtime eater

<p>Vodacom has been chowing both my airtime and my data all at one. This is the second time this has happened. Last night I loaded R100 worth of airtime bought data but both my airtime and my data are finished when I call customer services I am told that I have background application which I didn't switch off and therefore I went into a vodacom store and they were switched off for me therefore I don't understand why this happening all over again</p>
