Paid order never delivered and order cannot be canceled

I placed an order on the app and paid for the order which was accepted by Kempton Park restaurant around 18:40. To my surprise the status of order was stuck at preparation stage. We'll, I thought they had high volume of orders and my order will take longer than expected. 2 hours later the status did not change. I tried to get hold of the restaurant and I couldn't. Used the chat feature on the app and the bot was not helpful. Called the call ce term around 20h20 the Nono promised to get the restaurant manager to call me which never happened. Out of frustration I called a gain and Sibongile told me that there is nothing she can do except to log a complaint and I will be refunded within 7 to 14business days. Which means I will get my money after 3 week because weekends are excluded. My son had to sleep with an empty stomach because he couldn't wait until I finished cooking. What an inconvenience!!!!
