Bad customer service

I was served by Caroline Muranda debonairs Victoria Rd grassy park, she was so rude . She even gave me a wrong order when I told her it was not my order she said I should have checked and I asked her if it was my duty to check orders or hers. She did not apologize but said Nxaaa.When I was leaving she said something to her colleagues and they laughed at me. That was my worst experience ever. She was rude from the beginning
