*********** and poor service

I have always loved Nandos Greenstone,Modderfontein drive but lately they have been stuffing up big time. I order from them at least twice a week. In the past three weeks they have got my order incorrect. The first time they gave me a breast when I ordered a leg. The second time they gave me a leg hot when I ordered extra hot. The third time I ordered two 1/4 chicken one mild and one extra hot; I received 2 mild. We called the store at 18:45 to explain that the order was incorrect. They then verified they had given us the wrong order and would send a driver with the correct order. It's 20:19 and still no delivery. They have called us and told us that the driver left the store 20 minutes ago. I live 15 minutes from the store so it's definitely not within the required time and there is no traffic at this time of the night.
