Complaint: About a charge for rs 7291, which i never used or never downloaded data

I have received a bill for Rs 7291 for alleged use of 11GB Data.

My laptop has 3GB free space.
If full 3GB capacity or greater than 3GB capacity is used, my laptop will crash.

There is no scope with my laptop to use 11GB.

By personally visiting the below addresses
1)BSNL Customer Service Center,
near p&t quarters, secunderabad
2)the Concerned officer in Cell One
billing complaints, paradise, secunderabad,

I gave a written complaint, that i have never used so much data,
So far there is no response.

I request you to look into the complaint immediately and correct the billing and restoration of my BSNL 3G Data Card service.

more details and facts about my complaint
a)There was never a warning to me in this regard
b)As per History from my BSNL 3G data card, the data is like below
uploaded data is 2.65GB, downloaded data is 1.49 GB
no where it says 11GB was downloaded
c)As per my plan 5GB data is discounted, but i never downloaded 11GB or fully utilized my 5GB discounted
d)The net speed was always ridiculously slow around 1Mbps, to download such huge data, it would take several days to download 11GB data


hope to hear from you
