Steers de deur, total disappointment

I bought online and when I went to collect my order, cashier requested more time since the cooking crew made one pack of wings instead of three. I waited and finally got my food. When I got home, I discovered that they gave me an incomplete order, I bought chips but they were not in the order. This is an inconvenience and very disappointing for a big franchise like steers to make such below grade mistakes.
