Vodacom depletes 1G data in 31 seconds with no explanation

<p>Over the last couple of days I have recharged my account with loads of data, which vodacom manages to deplete in a matter if seconds. When phoning their call centre, their consultant just presumes it's a setting on my phone... which I haven't changed at all. Then when I asked to speak to someone who is not going to give me a generic answer, he just sends me back into the queue to speak to another *********** person. Vodacom has ****** so much money from me in the form of data and no one can give me any anwsers, other than it's my settings or the internet, which of course explains nothing!</p>
