Poor customer service and staff got an attitude

Today (02.09.2018) at about 14:00, my parents, son and I stopped at KFC in cape road. My mother and I went in to order some food. We took the 10 piece family meal with the 3 side added. The lady said to use that we will wait about 10 minutes, which we agreed too. We paid and got our slip with the number. We noticed that our number didn't appear on the TV that shows waiting / collect. As we were sitting waiting we noticed that peoe that came in after us was getting there food and leaving. There was 4 barrols that was ordered after us that went out. The numbers that was called was in the 100s and we were number 98(if I remember correctly) went up and asked what's going on and the lady just said they waiting for the chicken. So went and sat down. Again more orders went out. So went up again and asked. This time it was said that it's people that ordered from the window that came in to collect but once again numbers higher then ours. We took one of the packets and said, there is five pieces of chicken, get the other five and get the 3 sides so we can go. The lady behind the counter just ignored us and then spoke in Xhosa to her colleagues. Asked for our money back and refused to give it back, ignored us once again. Asked again and ignored. Asked for the Manger and refused to call her manager. Asked again for the money and gave it after how many times asking nicely. The service was very poor and the staff doesn't know how to treat customers.
