Owner doesn’t return security deposit

Want to make aware to people how to know which type of owner doesn’t return security deposit. The owner will always demand rent on 1st even when your rent date is on 5th. The owner only cares about taking rent no matter if you’re facing some situation. If you say take the last month of rent from the security deposit he will still insist on asking rent saying will pay when you leave. He always spam call for rent like a jobless person. While looking for rent both the broker and owner didn’t mention anything that the room get flooded during rainy season. During last month of staying in rent he will always annoy you saying leave the rent as soon as possible they have to do wall colour etc. giving excuses I knew he wont return back the security deposit so i just paid little amount saying adjust the rest from security deposit (only way to make him stop spam call) P.S dont stay in the rent I have stayed if anyone is looking for rent around bhagwan nagar ask me the address of the rent to stay away from it.
