Incorrect order

I went to Steers at OR Tambo International Airport to buy lunch yesterday and I ordered quarter chicken meal, but they gave me an incorrect order, which I only saw when I arrived at the office. I am not happy with their lack of diligence, especially because it was not full in their store. I had to give the 2 wacky Wednesday burgers away as my health doesn't allow me to indulge in burgers regularly. I am highly disappointed.
