Unable to recover Money from House owner after lease period expired

Hello people, i'm residing in chennai. I've been living in a leased accommodation for the past 11 months. The contract of the lease amounting to Rs 3 lakhs had a tenure of 11 months which was completed on the 15th of Jan 2019. The owner however now states that he has no money to repay my lease amount and is asking me to wait until he finds another tenet to fill the house. I have been pushing him for returning my money from the beginning of Sep 2018, and he just keeps giving me different dates stating he will return my money, but on the day, she come up with some reason to push the dates forward again. Unfortunately, the last time we spoke, she assured me that she will give me my money by the 15th of Jan 2019 and keeping that in mind, i took up another house for rent and have paid the new house owner the advance as well. i got a new job about a year ago and have to travel 25 kms one way from this old house to get to my office, i had to rent a new place to make it more feasible for me to commute on a daily basis. This is the reason i looked and found a new place and even paid the advance thinking i will move in as soon as i get my money back. My old owner now says nothing has come through and he can only pay me my money once he gets someone else in. i dont know how to proceed with this matter. I even tried telling him that i will file a case for legal action to be taken and she revolted back asking me to go ahead, he even threatened me stating that the case will go on for years and i'll never get my money back. I'm in a very desperate situation, I have borrowed loan from bank and paid as lease to my old house owner.Now im in situation to repay my all loans. I'm paying interest on this loan that i've taken every month. I was being nice and dint want to create a scene, but this owner seems to be taking me for a ride. This owner is politician in the particular area. He has no source of income for running her house. That being said, he owns 15-20 plots of land around and this house which has 2 floors. i live in the 2nd floor with my wife and 2 kids, and he stays on the first floor. Let me bring to your notice, that although he is politician, he is not subtle or approachable, he harasses us, shouts on top of her voice to make a point and is very abusive when i try to talk to him. he doesn't answer his phone calls when i try calling from my number and tries and avoids confrontation as much as he can. when we asked to return money in the month of September,he said that he would pledge/sell his property in the month of January to return my money.But he has not fulfilled the same. I'm in a very desperate situation, where i've taken loans, agreed on a new house for rent, and paying interest every month while my money is stuck with this House Owner. I dont know how to go about this, sometime i feel like just giving everything up . i want to know how can i pursue getting my money back and solving all my problems.
