DTDC Courier — Courier not received even after 7 days

Address:

Hyderabad, Andhra Pradesh

Hi,
I have given my documents to be couriered through DTDC services, for Kanpur.
Even after seven days , documents are not still received at my home in Kanpur(though its received at the office).
When we try calling them, either they dont pick up the phone or when receive , they say that
"we received it now and can you send somebody to take it."

When i call the relevant person here at hyderabad, at the first hand he doesn't talk properly, or he's not in office.

Courier no: H68490799
Date of dispatch: (25/03/2010)
Date of receipt (should have been maximum as what they communicated at the time of giving courier): 29/03/2010
