Vodafone India — service activated without my permission

Address:

Kamrup Metropolitan, Assam, 781001

Some stupid service activated in my mobile number without my permission, and the customer care replies arrogantly that I activated the service even though I didn't. Every month or do, they deduct some amount on this clause and they don't have a satisfactory reply. They keep looting the consumers for their personal benefit. I need the refund of my money from Vodafone
