Recovery of money given to franchise

I have given money for starting a play school to a franchise in Delhi and the owner told that within 14 days of signing the Agreement, Playschool will start. I paid the amount in the month of Feb. 2018 but the owner of the company had not started the play school till the end of May 2018. The owner keep giving dates and says school will start in just coming few weeks, and presently he says he will start it in the month of June-July 2018 which I believe he won't be opening the school at all. From his previous employee, I came to know that he had even fooled some other person too by taking the money and giving big promises but did not start the school. And when that person asked his money back, the franchise owner even threatened him and said money can't be returned. Now I am very much stressed and wanted to back out. I have transferred all my savings through online transaction to that school owner hoping to start a school and now nothing left with me. I want him to return my money and not to continue further. Can you please advice what steps should I take and how can I use legal steps in this situation?
