[Resolved]  Airtel India — deducting my balance on its own

Address:

East Delhi, Delhi

For past one week, my phone has been deducting my balance without me actually making a single call. Earlier they were cutting 10 paisa... now its moved to Rs. 2. 40 paise. The message keeps coming in with the amount it is deducting and my current balance.. The call duration is always shown zero. I have tried calling their customer care but none of their executives are busy. I had recharged my phone with 100 Rs and now i have .21 paise left in my account and at least half the amount has been self deducted (WITHOUT ME MAKING A SINGLE CALL)
Kindly look into my matter, its high time Airtel stop telling public how its the no. 1 telecommunication company and advertising it continuously.
