Exa Technology — threatening to pay the penalty

Address:

Karnal, Haryana, 132001

Exa technology company called me ones and asked me to register for their company. They asked me to send details of adhaar card photos of both sides and send me a sample of 15000 captcha which i have to solve it. But as i'm a student and don't have time to solve such i'm not able to complete my work on time.
The company is threatening me by calling from different numbers and some fraud advocates are asking to come to the court.

They are threatening me a lot. Please help me out of this...
