4th of the month my 1gb data plan renewed and I was using my phone like normal.
Few app updates here and there when not on wifi and some browsing etc.
Later in the week i purchased a 2degrees usb stick so my laptop could connect and opted to share data (since i realised that the 3gb of data included with the stick was useless to me being not within the mobile broadband zone at work).
Not sure how long it was connected but laptop browsed a few webpages etc and after 2 days of light use I see my data plan is sitting on 0gb!
No windows updates or anything turned on.
I have a job logged with 2degrees support about it since Tuesday but so far no updates on whats happened.
