Rude Manager refuses to replace incorrect order

I called Nandos south gate value mart for collection Saturday evening because they could not deliver, I orderd the Full chicken Hot with extra sauce and peri wedges. I took an uber to collect. When I got home they had given me the wrong order of a full chicken Lemon and Herb nothing else and when I called to correct them they had closed for the night. In in the morning the next day Sunday, I called at 11 am to complain. I spoke to the manager Collin who was very rude and refused to replace the order because I had eaten the lemon and herb. My argument is that I was hungry that's why I ordered the food and that's why I ate it. The rude manager Collin then said I should call the customer care as he cannot assist me. I have called the customer care line and awaiting feedback.
