Vacated the rented house after 6 years and 10 months; landlord is forcing to pay arbitrarily

I have been living in a rented accommodation (rent 27k with 2 month deposit) since April 2017, I vacated the house in January 2024. The house when I entered was not in that great condition. I mentioned the inefficiency and the old and some non operating fixtures to the staff of the landlord. Later I accepted the condition and moved ahead. I got many things fixed and had the house cleaned at my expense. Over the years also, I had the house painted, did major repairs like sewage cleaning, etc. the landlord never paid for anything but did minor maintenance in all these years just once, when wall had water leakage and a geyser replacement during the pandemic. I vacated the property on Feb 1st 2014, At the time of the handover of house, landlord asked to get washroom cleaned and some minor repairs. I agreed for cleaning, but asked some of the other repair unreasonable as it was handed to me in older condition n I had infact got it repaired initially. Some of it even not damaged. After a few days, he shared several bills including repairs (total bill so far is around 23k) of some fixtures that was old but not damaged and the cost of deep cleaning of whole house. I have some pictures of the house condition when I entered including the old taps and the dirty condition of bedroom. The landlord is forcing me now to cover all the expenses including normal wear and tear. Further, he asked me to clear the maintenance bill of whole house knowing that there are two floors for the last 3 years. He used to pay the maintenance bills from 2017 till 2021. The pending bill is of 72k as of January 2024. Surprisingly, my rent agreement clearly states that my rental of 27k includes the maintenance. I shared the screenshot but he is not listening. He is also not taking my calls and only send bill on WhatsApp. I had a deposit of around 24k after deducting the last months rent of 35k with landlord. Today, I gave up to his demand and asked to adjust my remaining deposit. In return he said that it’s not even the 25% of the cost. I then shared the old pics with the room and fixtures condition. I also spoke to this representative that handed me the keys and reminded him of the condition n he agreed that except painting nothing was changed at that time. Can someone please help what steps shall I take as I trusted him and respected him and never thought that he will ever behave such way. Thanks for any suggestions but please help me. It’s not the money but the way he is arbitrarily charging for all the work that is irrational. Just FYI, the house is more than 25 or 30 years old, the fixtures n all were not that old but definitely old as evident in the pics I have. I have all the conversation in WhatsApp.
