Monsterindia.com — Complaining about job in monster . Com on resume filling

I have joined the job without paying any registration fee at starting of joining in resume filling data typing. The work time is 6 days to complete the task and submit all the 600 resumes. I couldn't submit in time because of my exams. Now they were asking me to pay 7650 with GST, according to their agreement. If i couldn't pay the money then they will make a case on section 72, 73, 74 and they submit to court itself. Is it true? Or this is fraud? So that we people can pay the charges without delaying.
