Kolkata RPO — passport return issue.

Address:

Bolpur, Birbhum, West Bengal, 731235

My self arnab barui. From santiniketan, bolpur.
Last 2 moths i am out of station. For that reason i will not collect my pasport.
But right now i am in my house.
For collect the passport i am going 2 days ago in kolkata regional passport office and i will explain my problem.
But they say at first u collect the letter from your nearest post office after that you send me the letter by mail. But when i ask my nearest post office they say they will send the letter since 20 days ago.
From my house 150 km distance of rpo.
For that readon not possible to go repeatedly.
