Vodacom strikes again

<p>On Tuesday after speaking to vodacom about disappearing data I had over 1GB remaining on my account and I was advised to download my data manager which I did (I downloaded it via itunes and synced it to my phone) all was good and well until last night, when I received an sms notifying me I have 48 MB so I checked my balance and to my surprise it was true,so I checked on my data manager and it showed that since speaking to vodacom I had used 699MB and not my entire data?? So my question is are you still going to deny that data goes missing?? Your app shows that I used 699MB out of 1.2GB then where did the rest go??
