Ntech — fraud captcha work asking money

Respected sir,
On 24th July 2019 I joined into a captcha work after getting call from a unknown person. They told me to type 10000 captcha and I will get 20000 rupees. That person told me that he will take care that I need not to pay 5000 penalty. They told me to send adharcard proof and mail-id along with signature. As I have no adhar with me on urgency I have taken my friends adharcard Without my knowledge an agreement was prepared with scan of my signature. It has also no correct date which I checked after. Even though I believed them but after knowing my first day report I found that they are trying to cheat me. I got hesitated and don't know what to do. The person that contacted me is not answering my call.Upon searching about that company I came to know that it was afraid company. After 10 days they are asking me money and if not they will go legally.today I also got a mail from advocate named threatening me for money . I am poor student. I got so much worried plz help me.
