Missing data

<p>When I didn't receive my monthly data as per my contract agreement, I phoned 082111 and was told that at 00:20 on 1 October 2016, vodacom send me 500 mb. An hour later everything was used up. Now I was asleep at that time. They said my apps automatically update and that's why, but I did amend the settings. The same thing happened to my husband. ********** 394 and ********** 237. Now if that was the case, why only in October? We want our data back!</p>
