Delhivery — Parcel delivered to some other person in different city of india

Hi Team,
I had shipped an item from Bangalore to Uttrakhand. But unfortunately, my item was delivered to some other person as the Delhivery guy had misplaced the waybill number on my order.
So my order has gone to his address and he has come to mine address. But as a user, i haven't accepted his order but that guy has accepted my order.
He is not willing to return my order as he says first he need his order back.
I have even mailed multiple times to delhivery support team, but i didnt get any response from them.
As my package cost around 10k.
So please help me out in reporting this .
PFB the tracking number:
