Bad service

For the second time in a row I ordered shakin wings with bbq spice. Pay by debit card and then arrive at the pick up window where they tell you they only have the other flavour spices. (Tell me this at the window where I order and I'll just leave it then) Drove all the way back to work only to find 4 wings (FOR OVER R41) instead of the 8 I ordered. Phoned them, they took my adress and said they will deliver it. NOTHING WAS DELIVERED, not that I would want it now anyway. Train the staff or show if you are out of stock. That way I can decide if I still want something from KFC or not.
