Landlord is deducting extra money that was never discussed

Landlord is deducing money 5% increament for 19 months Hi There, I live in Bangalore and have lived in the same flat for almost 30 months as of today. I told my landlord last month that I'll vacate the place and he said okay. Background on rent agreement: Aug'22 to June'23 -> Had a rent agreement to pay 13500/- rent/month -> Deposit: 20k and 5% increment July'23 to Nov'23 -> no agreement was there and verbally discussed that the rent would be the same, so I was paying the same rent 13500/- Dec'23 to Oct'24 -> In Dec'23, the owner told me that he was going to increase the rent to 17k so If I wanted I can vacate the house or I can increase the deposit to total of 3 lakhs and stay here on same rent. So I did the same and we created a new agreement with 3 lakhs deposit and rent 13500/- and 5% increase after 11 months. I asked him couple of days back how much I'll get back from my deposit at that point he said that 5% increment is there and I didn't pay it so he will deduct the amount from the deposit for 19 months so a total of 32k I've to pay him extra. It was never agreed upon and he is not listening and challenging me to go to court or police if I don't agree. I told him that for 22 months we've agreement to pay only 13500 rent, so I can give for 8 months but he doesn't want to listen, just behaving rudely and not even talking to me or letting me involve my other neighbors. Could anyone please suggest what can I do here? Thanks in advance :)
