Bad Customer Service in township take away outlets

On 11 May 2018 I placed the order online at the Katlehong branch the time was 15:42 when I got the comfirmation that the store has accepted the order I clearly indicated that they must deliver at 17:30 , when I got home the pizza was not delivered yet, I waited at 18:30 I called the store and they told me that their driver just left and I will get the delivery soon I then asked them why is it late because the store received my order at 15:42 , They said that they had other deliveries that they had received an hour before my so my order had to wait but the driver is on his way. Its 18:53 now and I have not received anything
