First of all let me welcome you to this knowledge sharing forum. Here you can seek guidance and you can guide others also.
In India there is no legal sanctity for the Bonds. Hence it is illegal to get signature on Bonds as well they do not have any right to hold back your original Academic Certificates with them. After due verification they have to return back the originals to you.
Please approach some good lawyer, who can help you in getting the Original Academic certificates and your other benefits. In case your F&F Settlement Payment is not effected, then you can approach the court of law, for which also the Lawyer can guide you.
While going to the lawyer, please carry the following things with you.
Your Offer of employment
Your Appointment letter on probation
Your appointment letter on confirmation
Your Salary Slips
Your PF Details
Original Documents submission proof.
