Usys Services — problem with online data entry works

I'm a jobseeker in banglore. As i was phoned by the usys servies and was asked to fill some 3000 forms as data entry work. They said me that i would get an amount of 30, 000/_. I thought that it'll be helpful for my expenses and my parents. But, later filling some forms, i had gone through google and had seen some mails that it's a fake one. And, this day i'm so afraid. Please, help me to get out of this. The thing for what i afraid is, they have my aadhar card details and that's why i'm so tensed. Please, help me.
Even after starting my work also someone else also called me as they belonged to this company and said the same details. I told them i m already working in the same. Then they immediately cut off my call from then i started to doubt this and i am unable figure out what is the problem.
