BAD SERVICE NANDOS DENLYN MAMELODI

Bad service..l was so disappointed. I ordered food via phone and l was given a Reference Number and the time to go and collect. I even received a message on my phone to confirm the. I then send someone to pick up the order for me as l was still busy at the time. They told the lady to queue and re-order and wait again for the order. What is the purpose of purpose of ordering if when you arrive they tell you to re-test?
