Nandos Springs poor customer service...

I called Nando's to place an order in Springs. The nice lady who took my order was very nice, polite and helpful. She told me my order will get ready in 15-20 minutes. Okay I drove from my house which is like 30 min to the restaurant. When I got there well was told my order wasn't out yet, okay I waited as I could see they were very busy. I waited for another hour straight people came in after me and also left after me...the ladies there working in front are very rude, they act like they were forced to come work there. I stood there waiting for my order and when a man comes then they are very quick to come and assist him to get his order whilst you stand there like an idiot. After thr hour passed I went to the cashier to tell her I would like to cancel my order as I felt that was not fair, as I called then expected to wait for an hour??? She Just took my receipt went to her fellow rude colleagues then came back after a few minutes and said "here is your order" with attitude no sorry nothing. I took the food as I had hungry kids waiting for their food at home. But I must say I'm appalled by the way I was treated there and I paid for that food to be treated like they were giving it to me for free...my family and I love Nandos but I would rather drive for an hour than to ever go back to NANDOS SPRINGS. Management must take those rude ladies for a customer service course because...WOWWW!!
