Rudest check in guy no manager available

Just checked at cape town airport for my flight back to lanceria it was the rudest check in guy I have ever met he was so rude by saying he was already closed and I had to make my voice heard before he decided to help me I asked where I was seated he just ignored me. And then I wanted to see a manager there was no manager available they don't work o a weekend will never ever fly kulula again worst experience ever.
