This is actual proceedure for the PF get transfered-
If you have joined and left company A, and joined company B its your responsiblity to transfer your previous a/c to present one. That is company B. But once you join Company B you need to submit your Form 2 (Nomination Form) and Form 13 (Transfer Form) to your present employer(B) and then they have send this Form to your previous employer(A) where they have to attach your yearly contribution Statement (Form 3A) (See to that your previous employer (A) do the same without fail. Sometimes they will not do the proceedure or they will loose the papers) then B will send (follow up is needed every time) it to your regional pf office for further process. After 2 months have an enquiry with pf office through B whether your a/c has been transfered or not. if not do the same proceedure once again still it is not happening then directly give your transfer letter to the pf office through your present employer. Once all the amount comes to your present (B) account then you can do the same proceedure as you have done earlier. or if the amount has not come to one account (B) then you can apply for 2 transfer form for both the A & B through C
I hope this clarifies you.
Hope you get your pf amount at the earliest
