Transfer Of Pf Amount - Pf Transfer

i have changed from company to company four times in the past 7 years
every time a new pf account is opened
the amount deposited in the previous company's pf/fpf account was not transferred to the new company
should i widraw the pf amount or transfer to my present company?
how to transfer multiple pf accounts to the existing company?

Dear Member,
You can use form 13 for transferring the PF amount. In case of multiple P accounts use different forms. And please visit labour office before doing this for clarification.
