My landlord is asking me to vacate house

My rent agreement is expiring on 30th June and I have requested my landlord multiple times to extend the rent agreement for 2 months either through notarized or registered rent agreement and extend our stay for next 43 days till 12th August since I have got a job in another city and my joining date is 19th August. I am single female with elderly parents and not able to find any accommodation for 43 days. Initially he agreed to extend it but now he is not ready to cooperate in any way. He mentally harassed me on calls and forced me to pay more rent than what's mentioned in the agreement. I also got to know that he had also started looking for a tenant on Magic Bricks in February (almost 4 months before the expiration of our agreement) with immediate availability. He has also taken security deposit of 75,000/- which he is not ready to return in full. I have paid my rent in full w.e.f. Sept'22 till May'23 and all my electricity bills are paid on time. The owner has a bad history of extracting money or not returning someone's money on some or the other false grounds. How should I tackle this matter since his intention is to evict us from the house and also keep a larger part of security deposit with himself despite the fact that we have kept his house in a very good condition. Also, since I am on notice period, the company has also hold my salary until last day in the company
