Data depletion

<p>Could someone please tell me how almost a gig of data depletes in less than 24 hours, with the cellular data turned off for every app?</p> <p>I was sitting in the Telkom shop and my phones data depleted in front of the one guy who works there. I also at the same time showed him how no apps had cellular data on.</p> <p>Then I get on the phone with technical support and all they can say is "yes ma'am we can see how fast the data is going but we cannot tell you what the problem is, maybe you should go to iPhone" ... um, no this is CLEARLY a network problem and I'm ready to change over to another network as I cannot afford 100 rand of data everyday that I can't even use for myself.</p> <p>If I could have some kind of useful response, this time, that would be great.</p>
