I ordered on the app...

I ordered on the app/kiosk inside kfc in highveld mall the staff deleted my order on their screen requested a slip from me which I did not even see I saw a message with order number according to her I am supposed to know that I need to submit the slip to her Okay pass that the wings I ordered were horrible not fresh they tasted like they were made last week couldn't even eat them had to throw them away What a waste of my money there
