Landlord not returning the lease amount

I have paid 7.5 lakhs as lease on 2018. I have renewed lease agreement every 11 months since then. I have verbally informed my owner at October 2021, that I want to vacate the house as I got job in Bangalore and they want me to come to office daily. Since then it has been 6 months still my house owner is not returning money. Everytime when enquired, he is saying he will give in one week. Last week when we went to ask money, he started raising his voice and spoke very rudely. He is saying "Why wre you asking money. I have only give house as lease to you, i didn't borrow any money from you. Everytime when you are asking for money, I am getting irritated. I can give you money only if new tenant comes. Till then you need to wait or go and do whatever you want". These are only few things which he mentioned. If we say we will go legally, he is saying I know to manage legal things. I have connections with judges, police and politicians. You can try your best, I know to get out of this. I have shared multiple contacts for tenants, he has been speaking rudely to everyone and when i followup with those contacts all are saying that the owner is speaking rudely and we cannot live there. I have to get admission for my 3.5 yr old daughter in a school and look for a house nearby school. Due to my current stucked up situation, I am not able to move away from my house. And the way he started threatening, we feel unsafe to stay here. Any help will be useful as we are unable to find any solution.
