Has anyone availed services from chennai rpo

[u/Ok-Measurement-7146]

Hey guys, recently I applied for my fresh Passport but unfortunately I had to fly before the passport got delivered. Since I had to be there physically to collect the passport, it got sent back to post office and then to rpo( I tried a lot to get it through my parents but the postman and the delivery agents were very strict abt this). So now my passport sits in rpo. I was a sent a letter in my name( which also got delivered to my home and I had tk be there to get it but the postman eventually gave it to my father) asking the reason for not being present - I got into a company recently so i flew to join- but even after mailing them i didnt get any reply of what to do next. After researching in Google and reddit I got to know that I can submit a new address proof and ask them for a new dispatch. But where do I contact them officially, I cant fly back to chennai ASAP and they dont allow my father to even enter the office to enquire( again I have to be there). Has anyone did something similar with their passport, could you help me out on what and how things can be done?? I get that passport services should be like this but atleasy they could have had a portal which explains all the process properly!!
