Need information about PF

My former employer has not given me my PF number even after 1 year despite several request what can i do? (Sorry this question is not related with trading but here people help that’s why i asked). How i can withdraw my PF?

Raise a complaint with PF commissioner.
Alternatively, If you can get access to unified portal of EPFO then also you should be able to see it assuming your employer is depositing it in EPF.

Assuming your employer actually made PF contributions from what was deducted from your salary. If they defrauded you - you need to find recourse.
