Horrible McDonald’s service!!!!

I went to McDonald’s at Jean crossing with my children to eat lunch. We placed our order with the cashier and I handed her cash money and told her I would swip my card for the rest of the money, to which she agreed. Then she rang up the whole transaction as cash and asked me to swipe my card as well. So I asked her why am I swiping my card when the order was closed she said “my till will be short of I don’t swipe the full. The difference that I had said I would swipe for was R70 and she was telling me to swipe for R200. She refused to the call the manager when I asked her to instead she called another cashier and he then was like we can sell you a meal for R70 you must swipe for it but you won’t get it. I asked him to call the manager so that the transaction can be voided and he said she would get into trouble if they called the manager. I had been there for 45 minutes at this point with no food but money was out of my bank account. Eventually they both called the manager and she did a refund for all four meals and gave me the money back. She then took my order again and I swiped my card again!!! Had to wait 10 minutes for the meals and then the food they gave me was cold.... I asked them for fresh meals and the manager made me wait. I don’t understand why they couldn’t do the right thing from the start!! My kids were hungry and had to wait so long! I’m never coming here again!!! Why is McDonald’s not training their staff properly?! Why should I wait for 1 1/2 hours to get a meal?!! McDonald’s your service is horrible!!
