Gave money for website building now person not refunding or working.

I had given 2000 as a token for website building to Mr. Aman Ojha a month back. After my initial payment he dissappered and his phones were switched off and he was to found nowhere. I had to resort contacting his ex employer as Mr. Aman acted as an employee for the same agency we had contacted a few months back, but upon checking with the companu, we were told that he was fired for forgery and cheating. after a day we got a call back from Mr Aman to explain us why he disappeared, and told us how he is in deep trouble with some conflicts and also someone from his family has a major problem. As humans we still entrusted him and gave him some time for him to prepare us a template within a day or two.Mr. Aman disappeard again only to start messaging me on WhatsApp late at night on a Saturday to ask for money to pay his CREDIT CARD DUES. He asked us for 1200 rupees, it is when we understood that he is a fraud and it's better for us to back out of it. It's when I had a conversation with another member of our company, though the other member was still optimistic and called him for a meeting at our office to finalise the website. and Mr. Ojha accepted to come but never showed up. now after a week o two upon contacting him He started cursing and threatening us by asking for ₹21000 more as it was an amount had to be paid by us upon completion of the project. Mr Ojha tried making a lot of excuse aND behaved with utmost respect until we reused him money because of his unethical ways of committing business deals. The issue is not because of the money which is a mere ₹2000 but more because of his treatment and threats. And especially because he cant see his own fault in ways how he conducts his business. His ex employer also fired him for forgery and stealing money from them. Kindly help us teach this man a lesson before he ends up cheating more people like us and his ex employer
