Address:

New Delhi, Delhi, 110002

I have booked my courier on dtdc at 8 april at 11 am the delivery is yet to be done on 12 april and there is no where i can complain all they say is it happens, they charged 140/- for flight charges and cannot deliver in 5 days.

Whenever i asked what is happening they say it will be delivered tommorow and then they just bang the phone. It showed in darya ganj for 4 days when i asked to give my courier back then also they declined
