Chicken licked bad customer service

Ive just had a very bad customer experience with Chicken chicken, corner noord and twist in Johannesburg and it was my first time buying from them and probably the last. I was given an order that was supposed to come with chips and when I complained I was told I should buy the chips instead . The lady was so rude and didn't even apologize for the wrong order. The order costs 92 rand but on the slip it's its written 93 rand
