EPFO — Submitted claim 4 times (3 times india post and one time by hand)

Address:

New Delhi, Delhi

DL/939126/105- This is my epf number. I have submitted claim 4 times and everytime EPFO dwarka delhi office says that we havent received it. They are so shameful guy when I submitted personally to their office and when I called up to know the status they said we haven't received your claim. I have proof of the acknowledgment too. What should I do. I try to call them everyday but they never pick up phone because the moment they enter the office they just hang up the phones so nobody can reach them. I would appreciate if you take my complaint seriously and do the needful. Thanks Sumit
