Airtel Mobile
Charges even when the call do not go through

I am a subscriber of Airtel mobile. I noticed that there are lot of charges for calls for short duration (3-15 sec/pulses).

On close scrutiny of many of my old bills, I found out that these charges are for calls that never went through or got connected.

I would imagine that this is a big racket by the telephone company as most people do not recall which calls actually goes through.

I wonder if there is any independent authority to Audit these "Short duration " calls.
