Ordered food, did not get my complete order, now

Ordered food, did not get my complete order, now they just not talking to me, I called twice to tell them my order was incomplete and still there is no service. My order cost me R439 and some change, and still they got the order wrong, and did not deliver my food as promised. My wife ordered a lemon and herb wrap, they brought a mild wrap, I ordered a extra hot half chicken meal, still waiting, don't know if they ran out of chicken. I called them immediately, no assistance, all they keep on saying is, we will sort it out, nothing, no help. But when they wanted to get paid it was fast. Now I understand why the delivery driver from Nanados wanted the slip back to go and pay on there side as he said. We use to go and sit and eat there, no more, the table stay dirty, even after the people left, then you have to go and look for someone to clean them, some people sit at those dirty tables with the dirty dishes on. That is why we started ordering out from them, just shows, service stays ****, if you are at there restaurant or your house, they don't know the meaning of service. Cant believe they never came back to even apologize or just say we will bring your chicken, nothing.
