I Net Solution — regarding penalty fees of rs.10000

Dear sir/madam,
I was searching for some reason online jobs and posted my resume at some job sites. One day a company i net solutions called me and asked me to pay rs.300 as registration fee and that i will be provided with a workload of 150 pages which had to be completed in 15 days and accuracy to be achieved is 90%. They sent me an agreement and asked for id proofs and gave me some user id and password but it never worked. Then i did all the work and when i submitted they said you didn't achieve the accuracy of 90% so you have to pay a penalty of rs.10000. Even when i said i am a student and you should atleast pay for the work i have done, they said it's not the company's fault. Now they are demanding for rs.1000 before tomorrow afternoon.
I worked for this job since i can't afford money but they are doing this. Please kindly help me.
