Data theft!??

<p>I am disgusted at how fast data has been used on my phone. I turn background data off, I turn data off itself, I have tried EVERYTHING to try and save data- no success. I am going through GBs of data every week with out me even using the phone. I request new data that just never comes through- Vodacom what is going on??!!! Feel cheated to the max!! no one is ever willing to assist me even ! </p>
