[Resolved]  First Flight Couriers — pan card delivered to wrong person and at wrong address

I applied for pan card myself. Nsdl issued and dispached the pan card on 29-july-2017 by first flight couriers pvt. Ltd courier vide airway bill no. B903z0972672. My address and phone number were mentioned in the courier.

While tracking the reference id, it shows that the courier has been delivered on 02-aug-2017 to some unknown person. No other details are present. While calling the customer care of the courier service, the representative is not receiving the call.

Only thing i want is my courier which is pan card. The important document like this has been handled badly by the courier service.
