PF account showing zero balance.

I worked with a private company for about 4 months.My PF was deducted from my salary for each month. The PF account was linked to my UAN after i left the company. I checked with the establishment and its payment details list. The list contains my name, but my PF account balance for that company shows zero balance. Why is it showing zero balance even after the PF being deposited in the account? Please guide. How can I claim that amount ?
Thanks.

wait for some time, in most of places, the UAN based contributions are getting delayed to updated in member's passbook

Hi,
Thank you!
But, how long that may take,any idea? My colleagues in the same company have received their PFs.
Also, I am able to track my current PF transactions for the new company.

Also, will i need to submit Form 19 or any other form to claim the Pf amount?
