MTNL Mumbai — Account usage too high

Hi,
I am facing this problem from the past 4-5 months now. My account usage is having problems. I am not using the net still there is 5-6 MB's o[censored]sage shown. Once I opened a yahoo page and I was charged 3 MB's for that. MTNL Mumbai is charging, I hope for the upload also which is against what they have written on their website. They say that they charge only for download but the way i am billed I think I am charged for upload also. I think there is a software problem with my account which shows very high usage inspite of me opening just a sigle page in the browser. I have made repeated compaints to MTNL help desk through mail but they are all in vain as no one understands anything in MTNL. They revert back with a tel no which never gets connected and i am not able to put my complaints through. I have mailed them more than 10 times but they dont know how to reply. Their call centers do nothing in this. They say they are to help us but no help is awarded from them. They dont take complaints too. They also give us some no which never gets connected. My no is 26140122.

I hope complaining here will give me some proper response or I need to send this mail to TRAI and DOT.

Regards
Milind Patel
