Once you left from the Organisation, you are supposed to claim full pf only and not advance. Or you can transfer your PF to your new employer. Both for claim or advance employer approval is must. In case if employer refuse to update DOE please write a request letter (through RPAD) them requesting them to approve and still if you don't get response you can it take further with the respective PF office with copy of the letter sent to your previous employer.
Employer has nothing to do with PAN card approval. Please ensure similar name in PAN card like Aadhar and employment name.
