Missing data and airtime

<p>I have a cellphone contract with vodacom. As of yesterday I had about 4gig worth of data and R200 airtime had been loaded onto my account. I woke up this morning and I browsed the internet. A few minutes my balance for airtime and data was 0. I calles the vodacom customer service no and I spoke to a lady called Ntibelleng. She said that her records reflect I have my updates on since yesterday that have been taking up all my airtime and data. I emphasized that at no point did I turn on the updates. When I got the phone for the 1st time I set the phone to update only through Wi-Fi. Apparently the updates are still taking place. Even after ending the call I still checked my settings and they had not changed. So I would like to know what has happened to my data and airtime because I'm not satisfied with the reason I was given. </p>
