Airtel — icon service

First of all, i'd like to put this to your notice, that airtel has been playing with it's customer by simply activating services without the notice of the customer. Sadly for the past few days, a service called icon service has been deducting my balance. I tried every possible way to stop this service, however airtel is not giving me any option to stop this service.
Please look into this matter.
