Bharti Airtel HP — Automatically Charged twice for some "Mitti Ke Rang " service without my confirmation

Address:

Mandi, Himachal Pradesh

My airtel no. +91 [protected] was automatically Charged (twice in a day) for some "Mitti Ke Rang" service without my confirmation. I've been charged twice -- Rs.20/20days and Rs.10/10days on 01-Jun-2011 for the same service, my balance amt. was in -ve and I WAS UNABLE TO MAKE AN IMPORTANT CALL.

It always happens like this:
- I get a call from the airtel
- I hear a song or something, and I end the call as quickly as I can
- At the end of the day, I've been charged for some useless VAS service I didn't ask for
- My balance gets in negative amount
- I'm unable to deactivate the service

The above incidence has happen to me more than 30 times and I've lost MORE THAN 1000 RUPEES. And it's intolerable now.
I want from Airtel to DEACTIVATE ALL VAS SERVICES & WAIVE ATLEAST RS.30 TO MY NUMBER and stop fooling its customers by such childish policies.
