Customer service refusal

Kfc taung, has no management because employees do not aim to serve customers with customer service and convince. When you get to the till point they direct to the self service terminal. Which does not have option to customize an order. Was sent back to the till point, in my observation the cashiers self serve themselves convince that is meant for the customer. Managers send shift supervisors to attend to complaints that requires them. They don't take the running of the store serious.
