Naukri.com — I'm complaining about fake job

I logged in to naukri.com 2 weeks ago and i applied for work from home, part time jobs. I got texts from the recruiter on WhatsApp from homebase work company where they provide you a project containing 100 images(pages) to type in a software in 7 days. She called me and explained the work and asked me to tranfer 2k, 1k for process and 1k for security issues(cashback if the project if rejected), if my project has 90% accuracy then i will get 10k but if rejected then will get 1k back and i transferred 2k via google pay and received the project. I worked so hard without sleep for a week and submitted my project on time without any delay. It's been 2 weeks now, I've been continuously calling and texting them( recruiter and helpline) i got a mail that my project is rejected saying space is the error in my workload without showing the report, thet just sent a mail rejected. But where is my cashback?? And there is no report justifying my project containing more than 10% of errors. I have been calling them but no response. Please help me get my 2k back.
