Bad Service at Nandos sunnypark

I called Nandos to make a pick up order at the sunnypark restaurant as i usually do, When collecting my order, i went to the collection point were a very rude staff member by the name of Sabelo refused to help me and said i should join the long que in the store. I told him that i have already placed my order and just came in to collect but the idiot would not hear me out, i have always experienced good service at this restaurant but today i was completely appauled by the bad service, it has completely turned me off. Nandos should really screen their staff when employing them, I am not going to spend my hard earned money in a store were i will be harrassed by these ill mannered people.
