unwanted subscriptions..... money drain.....

I received an SMS from AD-54321 on 7th Nov 2011 at 11.30 pm, saying "You have been renewed for Full Track subscription service from Airtel.You've been charged Rs.5."

I have never requested for any added services.
I also have been charged for unwanted services earlier I have never requested for.


Please Deactivate it Immediately.
Also return my money a.s.a.p.
