Company Has Lost Original Document And Breached The Contract

Hi Sir,
My current firm has lost my original 10th class marksheet which they had asked as a proof of Contract. They have mentioned that I will be placed in the New Delhi office, however I was placed in Gurgaon, which is in Haryana. Is it correct that besides saying that I will be based in New Delhi office I am based in Gurgaon, though I understand that New Delhi office can be any where, but can it be placed in another state? I am supposed to work at the New Delhi office which is located in Haryana, does this make sense?
What all laws have they broken apart from this being an Integrity issue and what can be the outcomes of this?
In the contract they had said that I will have to work for one month and give away my full salary if I leave before a year.
I decided to quit and then I was told that I can collect my document at the time of Full and Final settlement.
When I asked for the document as I had to present it somewhere else, I was told that the document has been lost.

The attitude of the company authorities is very astonishing. After having lost a certificate of an employee, the company is simply saying that it is lost!!! Really unethical and unprofessional. First of all, the company should not have collected the certificates in original as a surety and if collected, it should have kept it safe and if lost, should have the courtesy of making it available to the employee at any cost. The attitude of the company that you will receive everything along with full and final settlement is really upsetting also. Therefore, I would say that you should lodge a criminal compliant against the company before the local Police station. Any way if you want to apply for a duplicate, you should have copy of FIR. Therefore, do that.

Thanks Madhu,
I was really looking forward to this answer, in any case I will have to lodge an FIR to get a duplicate issued. You made my day. I have a meeting today with them, as per the contract I was supposed to work for a month without my salary. Today I will ask for my salary and for a letter from them that the document has been lost.
Thanks again Madhu, you evoked a sense of confidence in me, just an hour before I leave. :-)
God Bless!
