India Post — Parcel stuck at Netherlands customs for 1 month.

Consignment no. RM[protected]IN
On 4/10/2021 i sent a parcel to Netherlands via Registered Mail. The parcel reached Netherlands on 18/10/2021. But the parcel is stuck in Netherlands Custom clearance since 25 days.
PostNL only keeps telling me to start an investigation with IndiaPost. But india post keeps responding to me that the parcel is dispatched.
This situation is causing me a lot of mental stress as I'm left helpless.
ONLY WAY TO SPEED UP CUSTOM CLEARANCE IS IF INDIA POST REQUEST NETHERLANDS CUSTOM TO DO IT.

I REQUEST INDIA POST TO DO THIS AT QUICKEST.
