Mental harassment by landlord

Hi, Myself, my wife and my 6 year old son have rented a portion in an independent house 1 month back. From the day we moved in, my land lady (single 40 years old) has been harassing us for no reasons at all. - Shouts at us if we just open for our main door and insists on keeping the door closed. It is like a house arrest. - Do not let my 3 year old son to come out and play with kids in the neighbourhood. Made nuisance multiple times when my son is seen playing with other kids. Playing is basic right for a kid and she denies it. - Do not let me or my wife talk to any neighbours. She says if talk to anyone, she will file case against us. - Always stays in our corridor and keeps talking on phone in Tamil about us using bad words which we won't understand. - Whenever I open my mouth (e.g. to ask why a child can't play outside), she threatens me with police cases. She has already filed multiple false complaints against many neighbours in that neighbourhood, and I am worried she will do the same thing with our family also. I have decided to vacate that place, but I am worried that she will file false police complaints against me if I ask for return of my deposit. How can I get help in protecting our basic rights to freedom, peace, privacy and my child's right to play ? What are the government institutes which can help me in such cases ?
