Nobody can be that bad. They were supposed to deliver the parcel within 2 days but they didn't deliver for almost 4 days. And then while I ask them they just making the excuses and the attitude of the delivery boy is also rude. He just did not give the damn and I never used the courier service after that again because the parcel was needed to be deliver at time.
I strongly suggest donot use DTDC ever in your life. There are far better options.
