Domino's Pizza — order placed and paid but not delivered

Address:

92/C (Top Floor), Street Number-7, East Azad Nagar, New Delhi, Delhi, 110051

I have ordered two pizzas from domino's through zomato at 9:50 and didn't got those pizzas till now. I have called dominos so many times that my order is not delivered and they asked me to wait and wait and wait. And its about 3 hours that i am still waiting and all the telephone services are closed now. I have paid through paytm while ordering. My order number was 391, krishna nagar store, delhi. It was the worst service as my order is still not delivered although the dominos promises 30 mints delivery and after 3 hours i didn't got my order. And i have lost all hopes that my order will be delivered so, i not only want my refund but also i want domino's to give me concession on future orders due to all the inconveniences i faced and still facing.
