On 22 september in night at 1:28:02 am i got a message from 51234 that "You have been successfully subscribed to Cricket Dhanadan pack.Dial 51234123 for free to listen to cricket updates commentary, contest & more" while i have not sent any message or i have not done any call for activating this service.

And about 49 rupees has been added to my postpaid bill. As i didn't make any call or message for activating this service. I don't want this service. I want my money back.

This is very serious matter. Anyone suggest how to get my money back.
