Hi,Me too got into the same situation. But BSNL itself solved the issue.I got a bill of 6K, last month. Usually my bill will be 800Rs. What I do is that, I took the print-out of my i-net usage from bbservice.bsnl.in, for that particular month & marked those night usage, which they'd accidently billed. I went to the BB accountt-office & spoke with the Account Officer (AO). She checked my print-outs & figured out the mistake that creep into the night-usage calculation. She re-printed my bill & i's saved.That's my story. Like this, evrone has a story. Bcz, BSNL top-heads wants to sell their share to private companies.
