First Flight Couriers — not delivering the courier and not knowing the status

First flight courier agent took the courier after checking the pin code and confirming that it will be delivered in 4 days. However never delivered. On calling the delivery agents they are saying in is non serviceable pin code.

First of all there is no clarity within the company itself.

Original person who took the courier still maintains that it shall get delivered and has no clue what shall be done next. He is simply saying that we are just agents.

The item was tikka and should have reached in time. It has emotions and sentiments attached to it, which the company does not care about.
