India Post — Item stuck in north Lakhimpur post office since 20 days

I was sent a package from Delhi on 7th September . It was going smoothly but since 29th September my parcel is stuck at North Lakhimpur saying the item has been dispatched but I did not get any updates on it and even checked with my local post office (Naharlagun, Arunachal Pradesh) and it’s nowhere to be found.
Kindly look after the reason for the delay and fix the problem.
