First Flight Couriers — my product has not been delivered yet to given address

Address:

Bangalore, Karnataka, 560037

I have submitted the parcel on 22nd january, 2019. This is to be delivered to dhanbad from bangalore. I was told that it will reach in 4 to 5 working days but it has not reached yet at the time of writing this complaint. I tried by all means but not getting any positive response. I am following on everyday to whomever i can connect but of no use. This is a gift parcel which had to reach before 2nd feb, 2019 but still has not reached. It's been 17 days but no update.in firstflight site it's showing deliver to ranchi whereas it should reach dhanbad. I am afraid if i have lost the product by handing over to such courier service.
My consignment number is :
F991b4817101
I hope i will get some help by putting complaint here.
