First Flight Couriers — item missing from courier parcel

I booked a courier having consignment no. E[protected] for gurgaon on 28.04.2018 which contained 6 nos. Boxes and 3 nos. Packets but when delivered on 08.05.2018 only 4 nos. Box and 3 nos. Packets were inside the parcel.

It is to be noted that 2 nos. Boxes worth rs. 2000/- were missing from the parcel.

Please look into the matter and resolve the issue by locating the missing items at the earliest.
