Trai — unauthorized debit by tata sky and deactivation of account

My tata sky account got deactivated without any valid reason. I paid the monthly subscription for april and my subscription period ends only in the first week of may 2019. But tata sky deactivated my account after they wrongly debited charges from my account for "dish relocation" service. No such work was done as i live in a gated community where we share common dish.
