KFC wrong as orderd

I did a online order for a 9 piece at Langebaan KFC and when I went in to pay I asked them not go put in any breast meat and that's how the cashier sent it through to the people that pack the food and I got my order and went home when we were ready to eat we saw we only had 8 pieces and 5 out of the 8 were breast pieces so order was totally wrong even short a piece of chicken and as we stay a distance and was late aswell so we ate and enjoyed our meal was just up set that that mistake was made after we always buy there and do not really have problems with them
