KFC flamingo Square

The manager at Kfc in Flamingo Square Mall is very rude and unprofessional, she runs that franchise like a ****a shop. I bought the wrapsta box and before buying I was not made aware that their cooldrink machine was broken.She handed me my order without the cooldrink and I asked her where is the cooldrink and she was so uninterested in even talking, she told me that the machine was broken and I asked her to make a plan cause had she told me before paying then i would have went somewhere else and she said "oh well you must pay an extra R22 for a 500ml" when I refused she said oh well you can take your money back, how when I paid with a card. I asked her if she cannot take that 500ml and pour for me in a cup same size as the one I would have recieved with my meal and she blatantly refused, I will never ever buy anything ever again from KFC, the customer service is appaling. The staff acting all entitled to our money like they are doing us a favour. I should have went to MacD. why on earth would they make their problems my problems, if the machines are broken and they are not willing to improvise, they should shut down the franchise cause clearly they are failing and the manager has an attitude, she is so condascending and has no clue how to treat customers after selling food that is not as advertised.Even on google that branch has the worst reviews
