DTDC — Parcel missing

Address:

Bangalore, Karnataka

On 26th July 2015 my f riend send a Currier through DTDC from Bangalore to my office Indirapuram, Grhaziabad. But I didn't received it because some reason office was closed and DTDC Currier boy didn't call me and send it back to Bangalore. My friend was searching for that Currier and DTDC said it not came to them. Then where is my parcel? CN No.:- B22600593. Delivery boy should call me if office was closed. Now DTDC is responsible if my parcel is missing.
Please help me to find my missing parcel. I have mailed DTDC twice on 22nd July and 27th July. But they did not reply to me yet.
Thanks,
Avisek Maji
