Bad Service

I have a problem with KFC Meyerton when you phone them they never pick the phone up, you need to phone more then 6 times but on Sunday the 19 July I had enough of this bad service I phoned 15:00 they did not pick up the phone then I phoned the lady that normaly deliver our food and placed our oder with her. 16: 10 I received a phone call asking me if I have a problem I said no but we are still waiting for our food, the guy said to me to stay on the line, came back and said okay the problem was on their side but there will be no delivery, I said okay please prepare the food we will be there in 20 min. The guy told me no I can came and stand there in line and place my order and wait for it when we phone the delivery lady again she said she is still on duty and not alowed to go home. So my question is if there are no delivery why must the delivery peolple stay there and why if this problem where on their side why phone me and 1 hour later to tell me there wil be no delivery . This is not my first incident with this KFC!!!!
