DTDC — Broken Piece and Late delivery

Address:

Thane, Maharashtra

Sir/Madame, My complaint is in regard to late delivery of my parcel and that too in broken piece when they pre-checked my parcel in their office before shipping off the parcel. They assure me that it will be delivered in 4 working days. But to my horror, it was delivered 10 days( i.e shipped on 24th and delivered on the 4th of next month) exactly from the that I sent it. Please see my attachment for the receipt. The item was broken beyond any use. I call them up to address my concern but they have nothing to do with it....as told by the agent.
After much conversation and assurance that it will be delivered in one piece within the frame time, why all this happens. Is there any legal ways to fight them or its just their duty to lost ones' property without much to do from their sides....? Please help. If any information needed, let me know.

Thanking you.
