Data and Airtime balance incorrect

<p>I am extremely unhappy with the service from Vodacom. Your app doesn't want to work proper and every time I try checking my balances with *111# but it keeps saying there is a system error and that I can't view my balances currently. The problem is I have been connected to WiFi this past couple of days continuously (therefore not using my cellular data AT ALL). I also don't really ever use airtime. For the past two months I've been using my phone in exactly the same way so I don't understand what is happening. I had about 7GB of data and R380 airtime on my phone still last night. When I woke up this morning all my data and airtime is just gone. R0. 0GB. It is displaying my bill for my uChoose contract instead and this two days before the 1st (which is my debit date). How come my phone is just simply not usable for two days before it is supposed to reset for January?? This is absolutely shocking and unacceptable. And as for the lady Thsipo on the call centre - she wasn't really that keen to assist me and kept telling me that it must be an app on my phone. I strongly disagree as I track my usage and there is no way background data of one app can use 7GB and R380 in one night while I'm connected to WiFi and sleeping. I would like to know what happened to my data and airtime. Extremely unhappy!</p>
