Dear Alok,
If you have already taken your full & final then no need to be worry,please ask about to their legal consultant that what kind of file of are asking and also provide details about what kind of file you have given me in writing by mail or registered post? not
You should not give any anwser unless it is in written form,dont go their as you already left the organisation and join the other organisation.
I think you would not get your answer for the above question.
We will support you in this as we have our offices in all cities of India.
Have a good day.
Best Regards
