Dv Enterprises — threatening

Threatening me about filing a case against me through an illegal & fake contract.
I have joined the company through online process. One of their employee has called me & told how to work. They given me 1200 forms, which are to be filled within 8 days with 90% accuracy. I tried my best but couldn't complete. Now they are asking me for money as penalty. They are threatening me about filing a court case against me too.
When i searched the company on google, i found came to know that this is a fraud company. They are looting money from the general public. This company is full of complaints. I'm a student & i can't afford that huge amount of money. Please help me get out of this problem.
