Bigpond T-Bundle problems?

My mum recently bought the Bigpond T-Bundle that came with: 200gbs a month in internet usage, A T-box, and other phone discounts. Yesterday around 8pm I installed the T-Box to my TV and got it working with all the channels and wirelessly connected to my bigpond elite network gateway in the other room which currently has 4gbs a month. Today around 5pm I have gone to the bigpond website to look at the current usage for the month, and it is still at 4gbs....does anybody know why they have not upgraded it yet? I have alot of downloading to do =/ so thanks to anyone who can help! P.S All the cables are set and youtube and other applications on the T-Box work fine.
