Forceful eviction of the tenant for failing to pay the rent

Hi Sir,

I am staying in a shared apartment for the last six months. No tenancy contract. I couldn't pay the rent for August and September.

I have given a cheque dated 3rd October, but the landlord is behind me every day. Today, he changed the key and locked the room.

What should I do? He is not listening to me. He is shouting at me.
