DTDC Courier & Cargo — Items are missing in my parcel packet

I had sent some clothes to my sister from Begusarai, Bihar to JK Business school, Sohna road, Gurugram, Haryana. The parcel had some old trousers, one tshirt and a new hoodie of the brand being human. When she got the parcel, the packaging was not damaged at all but the tshirt and hoodie was missing. I request you to take immediate action as it is not a matter of clothes but a matter of security and trust ! There was also an empty poly bag inside the packet.
