Airtel — balance getting deducted every week

I am getting a message like "thanks for using crazy racer game. You have been charged for rs 10 from your airtel mobile account". This amount is getting deducted from every week and from last one year.. I am using basic phone and never activated these kind of services as my phone is not for these games. I want all my money back which was deducted due to this and want this deactivated right now. Please check the records and do it asap. Else i will move to other service providers. I am never able to connect to customer care. The call gets cut before starting.
