Airtel — games for service activation without permission

Address:	403802
Website:	www.airtel.in

I have been charged rupees 35 for 'Games fort' subscription, which I've never subscribed to or even heard of.
Please give prior notification even if it's a matter of 2 rupees, Airtel has been my choice since years and I have faith not only in the brand but also the costumer service team.
35 rupees isn't much to lose, but the question is wether you want to lose your customers for that amount.
Kindly look into it.
Thank you.
