Cheating by Travel Agency

Hi, I have bought a membership with one travel agency and they promised to provide a complimentary trip to Maldives with no additional charges applicable. I have paid the amount of 250000/- through online mode of transaction and confirmed my date of journey which is 18-20 Aug 2022 on 3rd July 2022. They said that it may take upto 12-15 days to send the booking confirmations. I waited till the time and tried to reach about my pending confirmations. Then they pushed the deadline twice and failed to update me on the status and then started not responding messages, calls from me. They promised saying that if any of their services are not satisfied then they will refund full amount. So, Since I was experiencing the mental stress about this problem it is affecting me both personally and professionally. So, I went to the office today to convey my dissatisfaction about the services they provide and claim my refund. But they are not ready to provide me the refund. Please help me with the steps I can follow and get my hard earned money back from this fraud company.
