Dominos Pizza — Bad service... Unable to deliver order

Address:	122001
Website:	Dominos pizza

I ordered pizza from dominos website on 11th March 2016 at 21:00 hrs (Order no. 414). The order was confirmed by them immediately. Dominos deliver pizza in 30 minutes as per their company policy. I waited for my order for 2.15 hrs till 23:15. I never received any update. finally I called them for the status of my order, they replied that they have missed the order and cannot deliver. I asked them why they didn't inform me beforehand so that I can plan my dinner accordingly. They were unable to provide any satisfactory answer.
This was a mess created by dominos team at sector 4 location Gurgaon. I just want to know if you are unable to deliver the services then why you take the orders. It was pathetic experience.
