Drive thru nightmare

KFC next to mall of the North Polokwane I am extremely disappointed with the drive-thru service at KFC Mall of the North in Polokwane. This is not my first complaint. I have previously raised the issue in store with different managers, yet nothing has improved. Today, I waited over 20 minutes before my order was even taken. This is unacceptable for a drive-thru service. As a regular customer, I expect reasonable waiting times and better service management. The repeated delays show a serious lack of urgency and customer care. I would appreciate feedback on what will be done to address this ongoing issue.
