Complaint regarding Form Filing Job Fraud

I was looking for online jobs in quikr. I got a call from a lady named Sxxxa Sxxxxxa from a company called SILI TECH regarding a data entry online job. The job was to fill 1400 forms within 10 days time with 90% accuracy. The salary offered was Rs 35000 and after that they would deduct Rs 7100 as registration fee. If I don’t achieve the accuracy or complete the work within 10 days, then they won’t provide me any salary rather I will have to give them 7100/- as Maintenance cost. She also asked me to send my Aadhar Card images and email id through WhatsApp. After that she let me to sign an agreement through OTP without letting me know that this agreement is for 11 months. Then they sent me Acceptance letter and Signed Agreement. The agreement seemed to be fake, since it had used fake Stamp Paper, without any security features. When I checked on internet, to my surprise, the images of same fake stamp paper were uploaded by other people also. These agreements had different company names as SILICON TECHNOLOGIES and ELITE etc. After carrying out an online survey of SILI TECH company, I also figured out that this company is not a registered company. Also I came to know that, various other people have also been cheated by offering ditto same job with same terms and conditions. After 10 days they start threatening you to pay money on the pretext of errors in job or Agreement breach. They also start threatening to send legal notice. Kindly look into this. Thank you.
