Shine Enterprises — Data Entry I'm complaining about fake data entry job from work on demand

I got an offer through work on shine Enterprises to work as data entry operator.They told me I have to fill 700 forms in 6 days and per form I will be given 25 ruppes so total I will be paid 17500.There is no registration fees so I thought it was not a bad idea to try.But the moment I finished 470 forms the I'd got blocked and they called me saying you have made a mistake while login logout and because of that your Id is blocked so you have to pay 3999 for ID reactivation and this amount will be refunded along with salary. So I told I didn't did mistake why should I pay for that and I didn't login 2 or 4 times after doing 470 they blocked .When I refused to pay they threatened me to take legal action so I got scared.so I call them and brother talk with them but they scold my brother and kept phone they even not ready to talk with my brother because they did mistake right so... Really I had worked hard to complete that forms but this people are frauds they playing with emotions and hardworking..and I even ask them u only pay 4000 after my salary I will pay to you but they said how can I give ma'am. so I told trust me and give ...they cannot pay money but they are stealing money from others
