Vodafone — Automatic activation of services without user consent

From few months VI has been automatically activating value added services like Fun portal, Callertunes and Handset mobile games. Which were not even accessed or selected by me. I am forcefully getting deducted in my balance when I don't even use those services. kindly requesting you to stop activating any services without users choice. And please kindly refund my amount which has been debited without my information. If this continues forced to port to other telecom networks.
