I have that as well but 35% of my usage got used in the last couple days.
Update - last two days, averaging 1.1GB per day which is within my 2GB daily average allowance. Decided to put a timer on my router during the day and ensure home PC is turned off. Wifey has a habit of leaving it on all the time. Will have to see what Rogers says about those spike days.
Now if I could just get my average water consumption below 2,000 litres per days
