Terrible service

I went to KFC Constantia Kloof,placed my order and was told to drive to 2nd window,1st window closed.2 cars in front of me.Placed my order at 07:42.Only got the 2nd window at 07:52. When I got there, they asked me my order again.I told them the order twice.I gave my money and received the slip.Saw on the slip they never added the chips.I then asked the lady to add the chips and gave her the money.At that time,I was already irritated as it was now 14 minutes since I placed my initial order.She then came and asked me to park for 2 minutes as they need to still make the chips.I asked my money back.I ordered a Latte and she asked me if I want white sugar or brown sugar,I told her twice I want 3 white sugars,I received 2 brown sugars.Also, the cup was only filled half and it was not a latte,it was a cappuccino.I saw on my slip also that she never rang up a snacker with patty,but am Riser. I left with the intention to go back as I could not still address the matter while I was there. I needed to get to work and had already spent 20 minutes at kfc.I had to give the burger away, as I do not eat the sauce that they put on the AM riser. This is unacceptable service.
