McDonald's Great North (Benoni)

Avoid McDonald's Great North (Benoni). I stopped for coffee at the drive-thru after repeating the order 9 times (not sure if it's faulty equipment or just the person taking the order) I confirmed the order at the pay section. The price for the coffee as displayed is R23-00 each and I had to pay an additional R1-50 for milk. (granted I did order Americano that does not come with milk) my total for the coffee came to R51-00 so R1-00 over. Got the order and drove away only to find that the milk had not been added as requested and paid for additionally. I made a u-turn and returned to complain. I walked in with the coffee and stood at the counter for several minutes with no one attending to me. I called out into the kitchen area to get service. The "lady" who came to assist (manager) I explained the situation and asked for the coffee I ordered to be fixed. She looked at the receipt and told me that the Americano does not come with milk so I explained for a second time that I asked for cold milk and paid for it. She took the coffee and brought me a coffee with hot milk. So once again I had to explain that I wanted cold milk. Seriously are they just too *********** or just have a don't care attitude or just don't understand instructions? So if you wish to avoid frustration and getting the wrong order while being overcharged for anything just avoid the McDonald's on Great North.
