First Flight Couriers — Parcel received in tempered condition with item missing

Address:

Darjeeling, West Bengal, 734001

I sent a parcel on 20th july 2016 from siliguri to kolkata through first flight courier but the parcel was not delivered until i contacted the courier agent in siliguri. When it was ultimately delivered on 27th july2016 it was received by the addresse in tampered condition and on opening the box later it was discovered that the item inside the box was missing. The addressee had refused to accept the parcel as it was in tampered condition but the delivery boy insisted that the addressee has to receive the parcel as he cannot take it back and he is not responsible for the parcel being tampered with. Under such circumstances i tried to contact the kolkata head office but failed to do so because none of the numbers are working. I also contacted the manager of siliguri first flight courier office (Hakimpara branch) mr. B. K singh over the phone but instead of listening to my grievance he misbehaved with me and refused to take any action regarding the missing item. Therefore let the necessary action be taken at the earliest by the concerned authority so that the missing item is retrieved and the main culprit be nabbed and punished.
