Unix Enterprise — calling for money again and again

I am a student. I was seeking for job. Then i found a writing forms task job by unix enterprise. But on the first day of my job, i told the company that i had fever. So i asked them that i want to leave the job. After some day, i received a notice that i have to pay 4500 rupees. Then they said to pay 9000 rupees. I was called by lawyer to pay or they will file a case against me. So, i had managed to collect money but i didn't tell my family about it. I took help from my friends and paid 9000 rupees to company. Now, they asked for 22000 rupees..
Please help me, i can't pay such huge amount.
I believe that you will definitely be there to get me out from this problem.
Waiting for your reply...
