Useless staff and service

I went to Westgate chicken Licken, we placed an order, "feed my craving". Thabo the guy who served us did not bother to greet us, he was very rude, to the order and did not bother to inform us that the wings were not ready. He moved out of the counter in his brown slippers and spoke to someone and came back to serve other customers. 30 minstrel later when we questioned why we haven't received our order he doesn't bother to attend to us as the person that initially served us. He straight out ignores us. His colleague only said "oh thank God I told my customers " no apology from anyone. Ended up asking for a refund. I can't believe I wasted 40mins of my time for nothing... you need to teach your staff customer service as they are nothing without us the clients. Imagine you waiting for almost an hour and not been advised of the situation i hope he will be getting a warning
