Disappointed

Hi I am at KFC Umphakathi mall I used the self service screen to order my food and paid there.I saw on the display screen that my food was being prepared then I went to wait in my car after 30 min. I came to collect and I learnt that my order was canceled , and I have been waiting for this food for 30 minutes now I had to wait another 15 minutes for them to prepare another meal. this is unacceptable, how can you cancel the order before it is collected yoh ai pls appreciate us as customers my lunch time got finished before I can even get the food
