Onlineworksjob — asking money payment to quit job

I tried to do online job at home. They sent 800 forms. sent an agreement on mail which i could not read bcz they were telling me on phone that how to do work. At the same time they sent some agreement.
The work is so tough, I said to quit the job they said u hv to pay penalty, I said no. they said legal action wud b taken.

I have not signed any agreement, still on talking to thsir advocate he cuts the call in between n says to come to court.Help me out I am stuck in this matter
