Worst customer service McDonald’s benoni Bunyan

Today I went to McDonald’s to buy 2 mcfeast meals. Only to realise later after, I have paid that they have added 4 cheese which I don’t remember requesting. While in the car waiting for my order I start Asking (Lady)packer of the meals and she says “yeh” which is very rude on top of that she tells me to get out of my car and go back to the guy where I ordered and tell him. Why should I be the one telling the guy when they are in the same building next to each other. I’m really disappointed with the lady attitude. In short she was rude. And doesn’t know what customer service is. The guy whom I ordered food from after his mistake he apologized. I was served by Mr Mdikwa A. I’m sorry I didn’t take the lady’s name but I guess he can give you the lady’s name since they were working together.
