Indian Postal Services — regarding missing or untraceable item coming from us through usps

Address:

Gpra Complex, 30,Type 3, West Tripura, Tripura, 799012

I had ordered the product from us through usps with tracking number uc[protected]us. The usps handles their parcels/posts to indian post as an unregistered post of indian parcel which is not trackable. I contacted to indian post for its whereabouts but they are unable to give any information (Infact they cannot tell the location of parcel received in india for the first time). Its been like 40 days from the shipment date (12/03/2019). All i get to know from delhi office is that the parcel could be lost or stolen. This is heights of non professionalism.
Kindly give me any details regarding product as it has valuable item.
