The same kind of situation happened to one of my friends and he was asked to submit P.F re authorisation form by P.F office and problem has been solved.
I have posted the authorisation form earlier upon one of our cite -Hr friends request, anyhow according to your request I am attaching P.F autorisation Form once again and changes to be done in this form as per your P.F office address where you are going to submit, since it is Bombay Based Form ( Form can be used across the country). You need to take signature from your ex-employer as well as you have to sign ( under yours faithfully column ) and submit the same to respective P.F office.
I wish you all the best.
