Dear Mssus54, while working in B Co, you have already filled the transfer form. However, since the status of the transfer is unknown, you need to check the same with the PF officials. Carry along with you the acknowledgment copy of the transfer request.
Withdrawal Process for Multiple Companies
If your amount has already been transferred to B Co's PF account, then you can fill the withdrawal form for B Co and C Co, as you have not transferred the B Co amount to C Co. Therefore, you need to fill out two withdrawal forms.
If your amount from A Co has not been transferred to B Co, then fill out three forms.
Hope this clears your doubts. Please reply back or call me at [Phone Number Removed For Privacy Reasons].
