Wrong Order and waiting over 45 minutes for my Meal

I went to Pedros yesterday after work and I ordered 3x Chicken Strips and Chips and a quarter Chicken Paella. My order too around 45 minutes to be prepared and when I asked why so long the order is taking, the lay said that there was a problem but when I looked on the TV screen i did not even see my order number available. After the long wait when I got home to eat our meal with my family I then saw that the order was incorrect. They had given me Chicken strips and spicy rice instead of chicken strips and chips. The family was hungry so we had to eat the meal which was supper. The kids were upset and wasted the food because they did not want the wrong meal prepared. I have the pictures and also the receipt of payment and a picture of the TV screen without my order number on it. I am really frustrated and would like to speak to the Area Branch Manager regarding this incident. I would like some Urgent Feedback regarding this incident because my kids and wife are very unhappy with the poor service that we received. Your Urgent response is highly appreciated.
