DTDC Courier & Cargo — leather sample

Address:

47 gobinda khatick road, Kolkata, West Bengal, 700046

On 26 friday, i booked a sample parcel on urgent next day delivery to gurgaon from kolkata. I was charged 710 rupees, my tracking number is v56659406. I was assured it would be delivered next day which is saturday the 27th oct. Till today it is not delivered. It is of no use even if it gets delivered.
How do you compensate for this?
Shouldnt urgent next day delivery be next day delivery. Kindly look into the matter and see what went wrong.
My client needed the leather to show to his buyers in china. He left on monday without carrying the sample with him. Do you understand how much loss is incurred due to your negligence.
