Terrible food and terrible service

I have had the worst experience at KFC Prieska. I bought food which wasn't fresh at all...dry buns, hardly any colonel dressing, and a chicken fillet which only covered one side of the bun. expired chips also. I have been a Shift Manager for KFC for more than 2 years, opening the new branch in Kathu at Shell garage in 2014. I know that YUM is extremely strict about Great Customer Service and just as strict about good food going out and I have always strived to make that happen! My experience here in Prieska was just terrible and Customer Service is not really helping much. When I went back to the store after work, Bernie at Prieska Branch was rude and arrogant and Customer Service haven't even bothered to send them a mail regarding my complaint. It's been more than a week since the insident and I still did not receive satisfactory feedback as promised. What happened to YUM's high standards when I was there? Are they making too much money so they don't have to care about customer complaints?
