My (and our customers) usage stats have been at the same values since 3rd March - called iBurst and it took me 2 days to convince them I was right!
Eventually iburst said "we are working on it..."
One customer showed 70MB available but he couldnt connect (as he actually had 0MB), so he bought a Booster and 4 days later it is still not reflecting on stats or usage emails (but can now connect).
So be careful, the stats are wrong but if you exeed usage you will be hard-capped, or rate-limited.
