Blue Dart Express — day definite delivery reaches on 3rd day evening

Address:	Bangalore, Karnataka
Website:	www.bluedart.com

I had a courier expected from bluedart on saturday on my company address.
Since it was official docuemnts company employee had provided company address itself and i was waiting for it on saturday at the office.

While (Over) smart bluedart employees finds out (May be from internet) that any way saturday is holiday for my company so they do not deliver "the day definite delivery" courier and insted shows up on monday.

They do not even consider to call and ask atleast.
I have one question to them :

What exactly day definite delivery means and if somebody paid for express delivery, why would they not consider holiday etc themselves and expect delivery two days late? It was a passport and had to cancel travel.
