Globaltalentjobs - Provided fake job offer at National University of Singapore and now persons of contact are out of co

Mr. Suraj with Contact number (+************) and email ID (hrsuraj@globaltalentjobs.com) contacted me in the month of December **** and told me that I have a job opening in Singapore National University as a Asst. Professor in Mechanical Engineering Department. He asked for confirmation by paying some registration amount of @*****/- . After this confirmation he handed over my case to Mr. Karan (+************) and email - rmkaran@globaltalentjobs.com as a PR Manager. At that time globaltalentsjob.com website was working and all the email IDs and phone numbers were working. Mr. Karan asked me for various fees and deposits on every stage of process (LMIA. ILMA, Profile and ID Verification, VISA process, Embassy work and travel arrangements). Total sum around Rs. *,**,***/- have been collected from me. Mean while they conducted two interviews through online mode from the domain of nus.sg. My interview was conducted by Ms. Anne Cole and Dr. Rajjaz Khan.
Last payment I have made in April **** for Embassy interview and travel arrangements of Rs. *,**,***/-. At this stage Mr. Karan told me that within fifteen days I will get appointment from embassy and then within next * days I will get an Appointment letter. Since then I called him and Mr. Suraj many times but Mr. Karan's phone was busy and Mr. Suraj's pphone was switched off. In the month of June and July I messaged him about cancellation of process and refund of money. He told me that previous contracts of NUS are ending up in August and I will get the appointment between ** to ** August ****. So I started calling them from ** August, **** but both the numbers are switched off and also I tried to send message through emails but emails are also showing that globaltalentjobs.com domain is not existing.
Now I am terribly worried about my money and the job.
