Domino's Pizza — refund my money back

Address:

Chennai, Tamil Nadu

hello On 6/07/2015 5:40 pm I ordered two pizzas to this address No. 7/5, Jai Nagar 17th cross street, Arumbakkam, Chennai through your mobile app. And the order amount is Rs. 763 and I paid it through my SBI debit card and the amount has been also debited form my account. Even after that I still didn't get the order confirmation mail or message Your mobile app is the dumbest app ever the only thing working is the payment gate way just get money from the customer and you dont deliver the order I thing you don't even bother taking orders from the customers. I checked the order history I could didnt find my last order then how could i hv a proof to show you I want immediate money refund
