Travel Agent Fraud

Hello sir, I am a victim of fraud by a Bangalore based Travel agent. I bought a package (6 Nights) to Maldives from a travel agent Oct 16. I paid him total Rs 300000/- for which he provided me hotel vouchers and airline tickets. My travel date was 11th Jan 2022 and return date was 17st Jan 2020. All the transactions were made online either through NEFT or google pay. All the communications were made on email, whatspp and phone calls (there was no face to face meeting) On 4th Jan 2022 night (few day before travel date), i got to know that airline tickets and hotel vouchers were fake when i tried to do web checkin on airline portal. Travel agent acknowledged on phone that there was some problem with the booking and then he stopped picking my calls for next 2-3 days. 3 days later he claimed that he will refund the amount. But he has not yet given any fixed date when he will do the refund. I would like to understand what are my options to firmly grab the travel agent ? Means apart from my principal amount, I want to claim amount for mental harassment caused to me and my wife due to fake travel tickets provided by the agent. Our trip was ruined just after our marriage.
