Wrong food

I don't even think words can discribe the anger I feel right now honestly... <br> <br> I went to the Kfc in vincent east london i order 3 Kfc salads get home and find 3 box masters I would just like to know how do you get that wrong I don't even eat this I had to force it down my throat I am horribly annoyed with the service I received keeping in ming I waited mor than 20 mins. .. this is not what u call customer service. I AM ****ED OFF!!! And what makes matters worse is the lady checked the order before giving it to me.
