well 24th and 25th usage can take time to come on the portal ( there is a delay SOMETIMES ) . There could be many reasons for this.
1)Someone else is using your account . To confirm this , switch off your modem completely for 1 day and the next day check your portal usage , if it shows usage during that day it means somebody else is using your account
2)Another possibility , is
windows updates,antivirus updates, some virus downloading files , somebody using internet through your insecure wifi network etc ...
A you mention about the time delay for 24 n 25th, I did check again today. After 23rd it jumps derectly to 26th. no usage is shown inspite of using the broadband. 23rd 3 times usage has been recorded inspite of my computer being switched on 22nd. Very strange to see this.
My wifi is secured and I have a security key for that. I really dont understand why this happens. Only on 26th I find the usage to be reasonable. like 12 MB for the 2 hrs I was online. It must be the case normally but 3.5 GB is extra ordinary usage.
Software updates is possible but I dont think windows vista home premium does so much in 1 week. On day 2 of installation I woke up at 4am and updated my system and windows showed me that its up to date. All done before 7 am. My system is new and possibility of virus is too less as it was hardly used.
I completely switched off the modem and checked, no usage is shown for that day.
I feel like some thing faulty is happening in BSNL system to show so much usage for no reason and show no usage for the days I used broadband.
There are mainly 2 possibilities
1. You can connect to internet by simply switching On your modem. ie, you need not enter user name and password using a dialer to connect to internet. In that case, if you keep your modem On and shutdown your computer the connection remains On and you will be charged.
2. Your computer has a virus infection. In that case your usage will go up exponentially. This can happen even if you have a firewall and a good antivirus. I changed svchost.exe settings to ask to avoid this.
The only way to avoid this is to monitor the usage regularly. BSNL sites may not be reliable for this. Most of us use a bandwidth meter for this purpose.

4 Ways to Check BSNL Broadband Usage
Since your usage is high, a written complaint with receipt to the Nodal officer or Appellate authority will be useful. You can find the address and phone no behind your phone bill.
Hope this helped.
Thanks for your reply. It was very usefull.
I do consider your point, but I too have a question. When you switch off your system completely, it is suppose to have no link to modem or technically internet is not used by the system to make any data or bytes to be transfer between the modem and the system.
When no byte transfer is possible how can one be charged?
I have a wireless enable/disable button in my system. when I move out of my system I disable wiress in my computer and enable when I come back. So I am techincally not using internet/ internet is not connected to my computer.
I really wonder how BSNL can charge for not using it?
I did make a complaint to local BSNL office and just waiting for them to reply me.
One officer responded saying such complaints came in 2005/2006 and nowadays we dont get it.
Dont know how to get out of this upcomming big bill.
