Airtel WAP Services
Can't unsubscribe from tashn.co.in

A month ago i subscribed some services on tashn.co.in and they gave a verification code on my mobile no 9903855922 and i gave it to their site after that Rs 20/- is deducted from my balance every week with no content downloaded from any site. Now that i can't find any unsubscribe link on that webpage.

Please help me in solving the problem.

Regards
