Miracle Software Systems — Withheld all my original education Certificates

I've worked with miracle software systems (VISAKHAPATNAM) for nearly 1 year and 6 months where I had a bond for 1 year 10 months and my reason for resignation is that the management is too horrible and unprofessional and even though they literally assigned me as a coordinator for the newly constructed building and follow-up with daily tasks about washroom tiles, doors, roof ceiling, air conditioners, chairs and tables (procurement) and I'm an employee not their office boy... Now this management without all of my original 10th, Intermediate ( 10+2) and my BTech orginal educational certificates and when I was asking about my certificates...they used to say to pay 60, 000/- rupees as breaking a bond agreement of 1 year and 10 month's and then wait for 15 days and come back to collect your certificates. They used to pay me 12000/- per month while I was working and how come they demand us to pay such a huge amount in return... This is too horrible... Till date I couldn't pay such a huge amount to release my certificates and because of that I couldn't get placed in other companies. Please someone help me with this concern...
