House woner cheated me

I was staid rent house for 42 months in Chennai at Porur. Advance rs 30000. Rent rs 6000 and for water charge per month rs 500. EB per unit 6rs. From 2018 January rent increases to 6500(with out proper intimation). There is no rental agreement. Apirl 28th 2018 I vacated house and headed over the key to house owner. While vacating house we asked the how much amount pending at that time owner said I will calculate and tell you later. After a week I called him and asked the advance amount at times said total amount rs 33650 so minus advance rs 30000 then balance I have to give rs 3650 like that he said. Then I went directly with common person. the following splitup he has given two months rent 14000, EB 2940, cleaning 2000, painting 9000, septic tank charge 2000, tripper charge 2000 , 5 switchs not working for that 500, one door stopper 100 and electrical labour 1110. Then we had long conversation and negotiation then he said I don't want give the balance amount rs 3650 after some the conversation finally he gave rs 2000 at that time asked him EB is not calculated properly then he said he will calculate and will give you the amount like that he said. Today I went asked him EB was wongly calculated 150 unit you charged extra give me rs 900. He shouted like anything he used two times bad words against me. he is arguing which he was calculated correct. I will not give money whatever you want you can do like that he said. So I returned back from that place. Please suggest me what shall I do next? In that house four tenant is there all are paying rs 6 per unit and there is no rent receipts and rental agreement.
