Dear Friend,
No need to get panic even being panic will not give you results.
What you need to do is just send mail to the top of the management of that company who holds your documents in original. Specify clearly that you already requested but got no response form the said department and if you will not get your originals back you will go to labour court and also file an FIR against them. Give them time line - say 15 days.
Sure you will get the response in a positive way, and If not, take the printout of the same attach your proof of job like appt. letter, payslips, bank statement where salary credits etc. and approach to the labour court with no wastage to time.
Chill HR!!
