Delhivery — Part of product missing at destination(Delhivery Direct)

This is regarding AWB[protected].
I sent this shipment from Vadodara to Bhavnagar. Initially, it took 2 days to pickup. And when it reached destination, part of product was missing on destination. The shipment was a big box along with a bag attached to it. But, on delivery, the bag was missing, which is an important part of my parcel.(without the bag, my parcel is useless)
I tried to reach and complain through the portal multiple times.But so far I haven't got any satisfactory response.(I already sent photos and videos with the bag attached to the parcel).
I raised my complaint through web portal, twitter handle and email to delhivery direct, but I have got nothing back.
It is now almost 15 days past and no response from delhivery direct.
