Vodafone India — Imposing of value added service without prior notice

My number has been activated for a service called Model Mania of Rs. 35 that I don't have a clue. Even the folks at customer have no idea bout such a service and they blame me for cliking a link. But I want to clearify that no such link or message came to me and so there is no question of clicking such link from my side. If this will continue in future I'll have move to other service provider.
