Nandos N1 Petroport

I placed my order on the Nandos call center for collection at around 17H20 to be collected at Nandos Petroport N1 as I was leaving Soweto for Hammanskraal;When I got to Petroport N1 Nandos I was told by the rude lady who was the manager on site that there's nothing they could do as my order didn't pop up on their screen;it's actually the Head office's fault.I mean I ordered my food 2 hours I could go and collect;So imagine the disappointment on my face
