Landlord not returning my deposit money

Hello sir, I had taken a house for rent. I decided to vacate the house in January. And i was suppose to inform the house owner 3 months prior. So I informed my owner over phone on 4Th Jan 2020 that I will be vacating the house on untill 4th April (so as per agreement i had to pay January, February and March rent). I paid January and February rent and i requested my house owner to deduct the March rent while returning the deposit amount It has been more than 6 months we are waiting for her Now she is saying she will not return the deposit amount till she get a new tenant /even now not responding to my phone calls . When I called from different number she picked the call and said that as long as I will not get a new tenant , I will not return deposit money(which is 35000). Problem now is she has done the rental agreement for the year but did not give the document or copy she has kept it with herself as she wanted that for some loan proof. I have asked her for rental agreement for 2019 but she argues she has given it to me. I have a rental agreement of 2018 with me and prior to that year. But i Can provide the proof of paying rent in 2019 as i have online transaction statements Sir, Please advise what should I do now as I need my money very urgently. What should I do now.
