Gave me off food

I ordered the 514 yesterday at 16:29 at Simply Asia in Boskruin. My partner wanted KFC so we went to get his food at the drive through. Must have taken about 7 mins max. We came back to Simply Asia to collect my order and it was already ready. Didn’t think anything of it at the time. Got home and when I wanted to eat, the food was smelling horrible and when I tasted it the chicken was off. I realized that they must given me someone else’s order that was probably left all day out in the heat. Took the food back and got my refund. I’m so disappointed because that used to be my favorite dish and now I’m really put off at the thought of eating it ever again. I’m also really angry that they thought it’s ok to pass along off food to me.
