If you've lent money and are struggling to get it back, especially if the borrower has disappeared, you have a few avenues to explore. You can file a complaint for cheating and breach of trust with the local police, providing any evidence you have like transaction details and chat logs. Even if you don't have a full address, the police can often trace the individual using their phone number. While recovering the money might be difficult, especially if given in cash without proof, the focus can be on ensuring the person learns a lesson for their dishonest behaviour.
