Dear Rajusiachen,
You are totally right, if any person submitted his PF withdrawl form to his organisation, he can claim his acknowledgement copy from his employer, to understand his PF status, afterwards he can follow up with PF department with this ack copy and ask for his PF amount and same time if he feels any difficulties then he need to contact with PF commissioner of the PF department.
Kindly confirm from your organisation for your PF status and at same time ask for acknowledgement copy or you can also check your PF status through online(If you know your PF Account no and establishment code).
Regards
Dipak
