India Post — Post still stuck in India

I had posted a foreign Registered Post letter to USA in RS[protected]IN on 11.10.2022 with proper custom declaration . As I am checking it status, the post is stuck at Kolkata AP TMO building since 15.10.2022 and that status is not yet updated. It is a letter addressed to Pushcart Prize, USA from Moramee Das Assam India.

Kindly look after the matter. What is the point of paying for Registered Post if it is delayed in such a way. Every time I have to send a post abroad I have to face such issues. Even though there was custom in Ghy office still same problem.
