R500 airtime 6gig data missing

<p>I had R500 airtime and 6gig data, Data that I checked this , this morning (6am) . My data had an expirey date of 1/4/2017 . But around 9am everything suddenly was reduced to 0.</p> <p> </p> <p>I called vodacom and the first consultant told me that my data expirey date has been reached, I then asked to be put through to his manager, in response to which I was sent to the review section and then the call ended.</p> <p> </p> <p>Upon my second call, the second consultant told me that I had used all my data over night, updating my phone (which is already up to date, via my WiFi at home with Mweb)</p> <p> </p> <p>My phone LG G5 has a setting set to only update software via WiFi and I was on my WiFi at home. So there's no way what the second consultant told me is true.</p> <p> </p> <p>I was then told the issue will be looked into, but I am not satisfied with what they believe happened (two different stories), is told to the solutions team.</p> <p> </p> <p>It's imposible that 6Gig of data and 500airtimecould even disapear in a phone update... the largest phone update is only 1 gig and there were no app updates being requested by my phone either, added to that, I was on my WiFi and the router is 3 feet away from my phone with my mobile data switched off.</p>
