Worst Service Ever

Last night, 13 December 2019, I called Debonairs Pizza Celtis Ridge to place an order for 2x large pizzas. This was at 20:11. A gentleman answered the phone and took my order details. Before taking my order, he confirmed my previous order and asked if I wanted to order the same thing, to which I rep**** no, and we proceeded with the new order. I was informed our order will be delivered in 45 minutes to an hour. An hour and a half later we were still waiting. I decided to call and find out where our order is. The lady took my number down and said she'll call me back after checking. 10 minutes later she calls me back asking if I received an SMS after placing my order. I did not receive it so I told her no. She then told me no sms means my order was not taken!! Aren't their calls recorded? How was I to know? Is it my fault? I called in, spoke to someone who confirmed my order details and delivery time. Was I supposed to call back and say I didn't receive the sms? Maybe I'm missing something. Does your website stipulate that customers should call back if no sms is received after placing an order via telephone? They could not even apologize for their oversight, my kids had to go to bed hungry. Bad and unprofessional customer service!
