Pathetic service at KFC opposite Woodbridge square

I've been sitting at the drive through of KFC opposite Woodbridge square kempton park for about an hour waiting to place and get my order. Kagugelo the lady that supposed to take my order didn't and told me I should go to the last window... When she took the guys order right behind me. The. When I get to the pay window the next lady takes the order but doesn't know her product knowledge because she couldn't give me prices for chickizza or the meal after demanding a price she takes out a sales receipt and calculates by hand how much each meal would cost... She tell me the price R76. 90 when I am about to give her the money she tellz me the price is actually R86. 90 she calculated wrong. Then when we get to pick up the meal the guy Abel gives me the box on its own with out a packet or cover... The. When I asked him it came across like it was an issue... He further then fogot to give me my water that I orderd with the meal and I had to wait another 20minutes for that to be given to me. How is this happening at a international francise. This is pathetic.
