I've received a Sms from Airtel "Thanks for using (subscription, TextBasedServices) subscription service on Airtel WAP. You've been charged Rs.20.Enjoy http://gofun.in

I want to unsubscribe this service which i never subscribed to.

This is highly unprofessional from behalf of Airtel.

My Cell no. is 919840843757.

Kindly look into the matter at the earliest and unsubscribe the service.
