KFC Manager's bad attitude

After coming home from a long day at work, I decided to send my son to KFC for dinner. We ordered a 10 piece family treat which came with sides (mini burgers, pops and wings). To my surprise, when my son arrived home with the meal, the wings were not in the bag. Being exhausted, I was so frustrated at the fact that I had to take a taxi back to KFC to collect the wings which were left out of the order. I requested to speak to the manager, her name is Selesi, who came and took my receipt from me and said she was going to investigate and went into their kitchen. I waited for over 30 mins without a word from Selesi and went home as it was getting late. Days later I went back to Selesi to request for feedback in her \investigation""; she also shouted that I should have waited for her when she went to investigate NO MATTER HOW LONG IT TOOK. I'm disappointed at how such an ***********; ill-mannered person can be employed to serve people;never mind into a managerial position. She gives the company a bad name."""
