Datails of amount transferred from pf account

In my view, usually the employer gets the annual statements of PF contributions which includes the interest amount and final balance at the year end, which should be given to employees. Check the same with your employer whether they have received such. Else, you may write to the concerned Regional PF Commissioner office requesting for the statement, if your friend claim is not more than 30 days old and wait for the statement for around 2-3weeks.

It is not possible now to ask the previous employer for the statement. 

The PF office is supposed to give a statement of your PF account to your employer every year, and your finance / accounts department is supposed to hand that over to you. But many employees never get this yearly statement. 1st check your document which you got from your employer.

Don't need to ask your previous employer.
