device and service provider not all that

<p>I recently upgraded. Couldn't wait to use my new S7. The phone has been using excessive data. 3 gigs in 4 days and R500 airtime.</p> <p>This is insane!!!!</p> <p>I have disabled every possible setting. </p> <p>On Sunday the 15th I went to Voda World, they could not find anything wrong. Was then referred to Samsung at Mall of Africa. They updated the OS and changed another setting and said all will be fine now.</p> <p> My phone consumed another gigs data from Sunday afternoon to Monday.</p> <p>I'm utterly disgusted with this.</p> <p> </p> <p>I would like another device and all my data and airtime refunded. There is clearly a problem with the device and or the networ****!!!!!</p>
