DTDC Courier & Cargo — courier not received

Address:	Pune, Maharashtra
Website:	dtdc.in

A courier from pune was sent to me by my friend. The courier had two books for my exams at 7th august and was really urgent to be received here.
The dtdc people obviously never delivered on time, and returned the courier back to pune. I dont have any books to study from my exams and the people dont know why it happened.
I call kanpur people, who tell me that the courier was not delivered due to wrong address on it, and when i call the pune courier service they tell me the delivery was attempted and not received by anyone, they also say that it asks for invoice (God knows which invoice is this).
