Financial pvt ltd not returning my money

I had deposited some x amount in this XYZ chit fund pvt ltd before demonetization. And now after all these months when i ask them to return my money they are not ready to return it. They are giving me Reasons like "We are in problem after demonetization" and hence can not give your money back for now. They are not paying the interest amount too after demonetization and when asked they are saying they cannot even pay interest amount and need time to pay my principle money. And after all these drama they want to pay me 10,000 each month as in my principle amount and no interest included. If calculated i should receive around 7000 as an interest per month for my principle amount. If they pay 10000/month its is going to take years to pay my principle amount that to without interest and it does not serve my purpose. As i kept that money aside as savings. I have paid tax to every rupee in that amount and deposited it legally. And i have a bond and a cheque leaf provided by them at the time of depositing as a proof. 1. What all legal action can be taken to recover my money. 2. What wil be the risk to my money if i take legal action on them? 3. How much maximum time it wil take to recover? 4.what can be the predicted result if i take action against them? Please please advice.
