Orix Enterprises — Orix enterprises

Respected sir,
I am a student I started work in orix enterprises one year ago in May at that time they charged me 300 rs/-, after paying that amount they asked me to send my id proof, passport size photo and my signature, after i send those to them they sent me an agreement with my photo copy and with my signature, and in that agreement they mentioned if you doesn't achieve 90% accuracy then you need to pay 10, 000 rs/- as utility charges, when i see that i was scared and and started the work, and i finally submitted the work on[protected] within the given time but, i got mails from orix enterprises that i didn't meet the required criteria, so i need to pay 10, 000 rs/- otherwise we will take it this legally and file a case on me, i was so scared by seeing that mail, and I paid Rs. 10000. And then they called me to pay lakhs of rupees. And after one year now they are calling me again. if this is really happened my whole life will be spoiled, please help me out this problem.
