Person not returning money and is neither responding

Story line: One of my female friend asked me to help her relative. I am not directly familiar with this person. But since I have a great bonding with this girl as a friend I sent that guy ₹10,000 as he was in need of money via Paytm on 26th Nov, 2022. After sending the money, this person was claiming that I mistakenly transferred money to his bank account which was dead (closed) so he couldn't retrieve that money. Now, when I ask him to return the money he never responds. He never picks up the phone call, never calls back and never responds to my whatsapp messages. Him not being able to retrieve the money shouldn't be my concern. My ₹10k was gone for him. Now, it is his moral responsibility too to return me. I also have his Aadhar Card as this stupid has put it up on his Paytm's DP. My concern: What can I do to make him return the money back? If I file an FIR with the transfer proof of Paytm record then what is going to happen? For just ₹10k, I cannot hire a lawyer. It's not that big of a sum. Even lawyer feel shall be more than this amount. But I need this money anyhow as I am in financial problems. What can be done?
