Rude staff

On Sunday at 8pm wanted to make a new card but unfortunately I received a rude service from a lady with a name tag Vuyiswa .She asked for my I.D then gave me a form to fill without asking if i had a card before or not. So she yelled at me as to why i didn't tell her that i had a card before, i tried to explain that i gave her my id so that she can check she still tried to argue then i felt irritated without showing and asked her to drop the argument as i found it uncalled for. I'm a long time customer of carnival city and they always had excellent service but the current stuff leaves a lot to be desired. Now I'm no longer sure if myself and family would still consider visiting carnival city ever again.
