Landlord not returning Deposit

Hi My name is Hitesh Singhvi. We shifted to Dubai on 26th Feb. Prior to that I was staying in Ghatkopar (West) Mumbai. I was staying in a rented 2.5 BHK apartment for almost 2 years and 3 months. The deposit of Rs.2.5 Lakhs was paid to the landlord through NEFT. The last paid rent was Rs 51500/-. My wife got a new job in Dubai. She has to serve 3 months notice in her previous company. As soon as she got the offer letter I informed the landlord on 13th December 2017 through whatsapp that we will be vacating the flat in Feb.. The exact date can't be informed as it depends on the Visa and ticket which will be sent by the company. Than again I informed him in Jan that we will vacate in Feb but the date is not finalised. In between he sent some brokers to show the flat for new tenants. At last when we got the tickets and Visa on 18th Feb I informed him that will be vacating on 26th Feb morning. He arranged one broker as well as her wife for the inspection and as he was not in town told me that deposit will be returned after his returning back. I didn't paid Feb month rent and requested him to deduct from Deposit. After that he sends a mail that he will deduct one month Rent Rs.51500 for notice period, Rs.50000/- for Repair and painting. Pl suggest what to do... He is not returning the deposit from past 3 months as he knows that I am in Dubai and no one else is there in Mumbai from my side. Can I file an online FIR against him. You can contact me on my India no +[deleted] or [deleted]
