Help regarding tenant-landlord issue stuff.

M21, M20 . It's been almost two years been in Chandigarh and have been with among various renter's in this city and all absolutely helpful to us bachelor's. Now. We are living in one room at rent around sec 41 and there had been problem regarding no water supply. Had to be because of air got stuck in Valve. We called our landlord asking for the same to help us and provide us relief with some plumber fixing work. His and her wife response: (tum rehte ho ab tum dekho plumber and all charges on you) We have already repaired some of the faucet of their home because all were not good in conditions and broke in few months. Always threatening us either fix it on your own or leave our house. We already have deposited ₹3,000 security deposit to them. In frustration I told them if we vacate this house we want our full security deposit and they took it as a threatening and came to place saying serving you (1 month notice period for the same) Now the issue is our bachelor's degree is getting over around April end and no one is going to allot us room for few months. We have been living here almost an year. He came and put his terms and conditions 1. No call and messages to me 2. Deal all problems on your own 3. Water or air whatever issues fix on your own In heat of the moment I did said I'll call police if you don't give us our security deposit and you haven't filled the tenant agreement form with us but we have proof of transaction for the same. But in reality we are scared to deal with police what if they come in their favour and ask us to vacate urgently and we have nowhere to go. We need your guidance. Pls give us your honest opinion.
