DTDC Courier & Cargo — non adherence to committed timelines

Address:

Amruthahalli, 560064

We paid rs. 300 for an urgent document to be couriered to mumbai via dtdc’s premium express service which guarantees a next day delivery. The same was not delivered the next day.
The staff at the office where we booked the courier from refuse to acknowledge a deficit in service and are not willing to provide a refund.
Request your kind help to facilitate the same.
Have lodged a complaint at the dtdc website and are yet to receive a response.
The details are as follows:
Your case no. Is 15222933 for dtdc c/n no. V55824898, we will revert soon with further details.
Cheers,
Roch
