2am-8am

Hi guys, From 3 year i am using BSNL broadband [BBG FN COMBO 500] in this i get 1.5 GB free in Day time, and i think 175 calls are free (not sure). Night unlimited from 2AM-8AM :) Speed = 2Mbps But these days, i have started using in day time more which reaches (crosses my free data of 1.5 GB)...

I recently subscribed for home 500 plan in bsnl , according to it i can d'load brtween 2am-8am free (ie without increasing the data transfer counter). But when i checked my account usage , i found that it has also added the amount of data i transfered between 2am-8am . Will I be charged for that...
