Airtel Prepaid Service
Forcefully provide unwanted value-aded service & balance deduction

I am using my Airtail perpaid connection mainly for internet browsing. Neither I use any other value added service nor I want to. But the company forcefully activating this services i.e. caller tune, miss calls alert etc without my knowledge and deducting charges from my balance. The customer care do not take this complain seriously and it is also very difficult to contact with them.
