Harassment by uncle of my landlord

I am residing in ghaziabad from last 2 years. My landlord doesn't stays here but his uncle stays in my neighbour. I was paying rent regularly sometimes thru bank transfer and sometimes thru cash. But the house condition was getting worse I requested the uncle for repair and pest control (which he promised before giving us the house). When I requested him for the repair he started harassing me. He put lock outside the big gate and only small gate we can use. Then he thru his driver started stocking me. He forcefully entered the house in my absence when my maid was alone at home. Then he installed a cctv outside. And started trespassing anyone who comes. One day he also brought 2 policemen to threaten me. After which I send an email to the policeman stating that I will vacate the house till 15th April and will clear my utility bills before that. I had some electricity due which I committed to fill in this month but he using his influence got my electricity disconnected. The department says that the man has complained against me. I stay alone with my son. Plz help me what shud I do.I don't have any rent agreement
