Paytm Mobile Solutions — fraudulent transaction

My paytm app has initiated a fraudulent renewal of subscription to woo app for a amount of 900rs without my permission. I have raised my concern with paytm, haven't received a positive reply so far. Further i'm not allowed to unsubscribe payment to woo app in my paytm app menu. Next deduction due is on 23/01/2018. I wonder how can paytm initiate a payment without my consent.
