KFC Witbank Mandela drive useless service

I went to get a meal at KFC Emelahleni on the corner of Mandela/Swartbos road at 20:30, 14 November 2017. I wanted to order a boxmaster meal. As I placed my order, the lady told me that they only have twisters available, I then asked why, dont you have stock? She rep****, we have switched off the ovens and that is what is left. I then said how is that possible, as you only close at 9pm? This is the third time that this has happened now to me, I go to order a meal at night and then you get the response of this is all that is available. I called for the manager and her reply was, If you want to wait a while, then we can make you a boxmaster. As I was already disappointed in the terrible service, I just said Im going to go to another place. When I placed my order, there were only 3 cars in front of me. It took over 30 minutes to get out of that drive thru as people were waiting forever to collect their food. I am really disappointed in KFC, this is turning into the worst franchise service in SA!!!
