Vacation Yaari - Fraud travel agents

I booked Vacation Yaari for a package to the northeast (Sikkim). They trapped me with the alluring package and asked me to deposit ***** INR to their account. I did it on April ** and have the proof as well.
They promised to send me the hotel vouchers post deposit of money but after I submitted the money, they stopped receiving my call and answering my messages on WhatsApp. I was able to talk to them on a few occasions afterwards but all they gave were excuses. Point of contact guy (Nikhil) talked to me on one day and I asked him to refund my money since I wasn't comfortable going ahead with them. His reply was not positive at all.
Nikhil (**********) and Priyanka (**********) were the points of contact from Vacation Yaari. They reached out to me for package info. I don't know who else is involved in this fraud scheme.
I am planning to lodge an FIR soon in case I don't hear from them. Also, will send a legal notice to them. I am also going to report their account number where I submitted the money. Details of which are as follow -
Account Name:- Vacation Yaari
Bank Name:- Central Bank of India
Account Number:- **********
Ifsc Code :- CBIN*******
In the meantime please let me know if someone has any better ideas to get me my money.
