Undeliverd food

Was looking forward to a wonderful pizza day with my family on Friday night after a long day at work. So I decided ro call the best pizza I could have Debonairs. It was on the 28th June 2019 at 17.57pm when I called Debonairs in kagiso mall on ***, I spoke with Katlego she assited me to place an order of a double Decca pizza barbeque flavour she told me it would be R159.00, her words was the purse will be take between 1or two hours. I said it's fine. I waited. I called an hour after the order i was answered by a voice over telling me the line is busy. I am actually upset, appalled by the bad service I received form Debonairs. I have been calling to check my order and its now 22.06pm I know I won't get my order because the restaurant closes at 21.30pm so I want to know what kind of service does a company,the food is never delivered, it is only empty premises that I received. Tell me how do u as debonairs can solve this inconvenience
