Waited over 35 minutes for 2 orders

We went to this KFC outlet in Jacaranda Centre on 23 July 2015. Olga was the employee that assisted us with our order. We paid at 8:25 pm for for the food, we ordered 3 box master meals with 1 famous bowl, 2 kiddies meals and 2 snack burgers. We got to of the box masters straight away and the kiddies meals with the snack burgers. The last box master and the famous bowl we waited for very long. At 8:55 pm we made a very big scene because we still have not received the last part of our order. Then Olga just ignored us and then she called Esther the manager. The rest of our food was ice cold when we eventually received the last part of our order. The snack burgers was so old it was very bad. It is the second time we went to this outlet and both times we had a bad experience. Then we phoned the call center to complain on Friday 24 July, they said someone will phone me within 24 hours.Still no one has contacted me to find out what happened or to apologize. This is so bad I can not even explain how I feel about KFC at the moment.
