Passport, Guwahati Passport Office
Passport not received

I have applied for passport in 2007. I have submitted all the requirements like police verification, bank draft etc in 2007. In April when my mother went to the Guwahati passport office the staff said that they have send the passport to my Bangalore address on 20th Feb but I have not received till today (07/01). I cant make a new Passport. The Passport is made in the following address:

URBASHI SAIKIA

C/O Mrs. Binu Pachani Saikia (Father's name: Mr. UTPAL Kr. SAIKIA)

KARANGA CHAMUA GAON

P.O Karanga
