Bad Attitude and No Feedback

On the 10 Feruaruy 2018 , I had an experience at the Greenstone Motor Valley KFC. Very sick with bronchitis and going the drive thru , the lady at the window nicely ignored me , so i proceeded to the window where she was. She then had the audacity to shout at me , that already offended me , and when I reacted she didn't like that. I noted she was the team leader of the branch (what a disgrace) and her name was Cebisile. I laid a complaint on the KFC page to which a lady from the call centre called and told me she has marked it for urgent feeback and sent it to the branch. A week later and still no feedback , and yet I go to this place every week? Is this the kind of customer service KFC strives for? And I bet nothing has been done to this rude "team leader" , is this really the face of the branch? I rather support a different franchise with staff who are properly trained and a franchise that actually cares about their customers feedback.
