India Post — Passbook lost and account number forgotten

Address:

Yeshwanthpur,Bangalore

I have lost my passbook and also forgotten the number i had opened account couple of years. I roamed about local, head office but no one gave me the right procedure. One post office had someone on leave so they sent me and covid time nothing could be done.

This is is hindering from me opening a new account as already account exists and also not helping me in getting old one as well.
