Worst Branch in Johannesburg

This is surely the worst branch in Johannesburg. So today I decided to go via the drive through thinking it would be quicker. Worst decision. Today around 8pm we order 8 and 4 zinger wings we waited for about 10 minutes for the car infront of us to collect its order. As soon as our turn to collect arrives, a different cashier attends to us and we are given 4 dunked wings. I tell her that this isn't our order so we wait another 5 - 8 minutes before our order arrives. This is not the 1st time i receive this kind of service from Ennerdale Kfc, there always has to be an issue everytime i order there. Please retrain your staff if needs be.
