Bad service

My partner and I went to Nandos Vereeniging,we order and sit down and when the waitress brought our orders mine was wrong i informed the lady but she gave me so much attitude before she return my order,when she brought the right order it was without source it was just braai meet no source on it,the unfortunate part i didn't take her name but we went to Nandos late at round about 7pm,I am not happy at all with the service received from Nandos Vereeniging yesterday it was really bad.
