Pathetic Service

The service I receive always when I order from Nando's in Sandton City is pathetic. On a number of occasions I order there is always something. I placed an order today @ 12:35 only for my order to get to me by 14:00. I called the store after an hour of not seeing any movement on my order on the app and after the Uber lady calling me telling there is a delay from the store with my order. When I called, I spoke to a lady called Lorraine who told me my order had left the store while the Uber was still waiting for it. I finally asked Lorraine how I can go about lodging a complaint and she seemed very clueless with their processes, all she could do was play blame game and say the issue was on the Uber side, I told her that was not the case as the Uber lady was in the store waiting with no one assisting and she therefore said sorry I don't know how you can lodge a complaint. The service is terrible and no one ever responds to complaints.. I am very disappoint and never foresee any future purchase from them again
