Really bad service I’m so disappointed no manager available, they shout at you and laugh

KFC SANDTON CITY bad service . I’m so disappointed with their service honestly Pamela and Ntokozo are playing with the system to suit their friends needs which I’m not sure what they getting in return. There’s a generated numbers by the system but they finish all numbers and assist people who are behind 1st and when you ask how it works, they laugh and speak in their language towards each other. Your number shows on collect order they tell u no number is working you must rejoin a queue that has too many people that came after you. And spent an hour just to get my order. Only to receive cold food and have pictures of what was served on the day
