Airtel prepaid mobile service
Re.30/- dedected without permission/without activationg service

I have not activated the Airtel Friends Chat service. I have received a message on 5th march @9.45 am. (Can I be your friend? Reply to this message at just Rs.2/- sms or check my profile at...). I have not send any sms to this service. But at 1:32 pm I have reecived message as (your friends chat id is 8653627. You have been charged Rs.30/- for 30 days.).

Without activating any service Airtel had deducted Rs.30/- from my account. So I want Rs.30/- back to add in my account balance.
