Domino's Pizza — No delivery of food and the outlet didn't pick up call.

Address:

Gautam Buddh Nagar, Uttar Pradesh

I had ordered food through the mobile app. The order was placed and i had recieved the confirmation mail. The food has not arived and the outlet where the order was placed didn't pick any of my calls. The order number 516 and the date is 17- april-2015. The name of the outlet is dominos pizza at sector 50 noida. The only purpose of writing this mail is that others don't face any problems due to there inconvinience. This is not the first time i have faced this issue. If i try to place order at any other branch they say that only sector 50 outlet has the authority to deliver. Kindly help me out in this.
