Data Usage In free Hours

I have data one Broad Band Connection with night 2.00 am to morning 8.00 am free

it shows in my usage that i have used about 150 three in limited usage timeperiod

but clearly the time is like 1:57 to 2:27 150... Mb

1:59 to 2:20 170..Mb

they are robbing us.

so either give them a wack or be carefull
