First Flight Couriers — product reached the destination hub but has not been delivered since 10 days

A courier was booked from pune to hyd roughly 550km on 6th august 2018.
it still has not been delivered to me . The tracker shows it has been dispatched and receiver a gachibowli branch but the courier service company seems to be unaware that goods once received in their branch are supposed to be delivered to the end customer.Its frustrating as no one answers the call in the branch office, please resolve this issue so that i can get my goods.
