DTDC Courier & Cargo — missing products

Address:

Ahmedabad, Gujarat

I had sent a courier to jaipur on 20th august 2018.
It included two bottles of perfumes, one football and four deodorants.
When the parcel was received two bottles of deodorants were missing.
Now the dtdc courier company is not ready to accept the complaint.
They say that it never happens.
On persistently saying that the items were missing, they started telling me that the parcel should have been opened in front of the courier boy and checked and then only signed.
But since it was a gift item, how will the recipient know what items were there in the parcels.
It was only after cross checking i got to know that two items were missing.

I then enquired about it with the dtdc courier company. But they are not giving any satisfying answer.
