Dedudction of money from the account unwantedly

Dear Sir,

I am getting SMS from 646110105 "Thanks for using subscription service on airtel WAP. you've charged Rs15"

I had not subscribed for text Based Sevice in Airtel WAP through http://igmobi.com. I am losing Rs 15/- per day for no benefits. I want to deactivate this subscription by tonight. Please be kind enough to deactivate this subscription by tonight. My cell no is 98662716
