Hi Rajneesh,
Harjeet and Ram have clearly explained the procedure for claiming of PF amount. Do as they have said. Employer cannot hold or stop claiming of your PF amount. You can complain to the PF office, if it is done so. You can ask / collect the acknowledgement from your Employer once it is submitted. Alternately, you may also personally submit the claim forms after obtaining the required attestations from your employer. Normally, PF office takes around 30 o 45 days for settling the PF amount. You can contact the office (PF), in case you do not get the same by that time.
Regarding your notice period, you can proceed as Harjeet explained.
Best Wishes,
Sindhe
