Terrible service from Nandos Waterfall

I'm very happy with the service I received from Nandos Waterfall today. I bought a full chicken which I asked them to cut and 2 salads. When I got home I discovered that there are only 5 pieces of chicken and the salads were not fresh. The veggies were very saggy and I had to throw them away, they look like they had been sitting for longer than they should have. I will definitely never purchase anything from them any more as I'm a very unhappy customer
