Late delivery

Yesterday, 11 March 2016, at approximately 18:42 I finally went through to place an order for delivery. At approx 19.35 I finally called Nando's to find what the delay was and I was told the delivery guy had already left with my order. I asked when he had left and the lady on the phone couldn't answer. She then said the guy had taken a lot of deliveries with him. I told her that if no one has arrived in 5 minutes i will not accept the order as i had started preparing alternative food for my family. Approximately 10 mins later the delivery guy arrived. Contrary to what the lady at Nando's had told me, the guys had done only one other delivery. I had been **** to. I felt sorry for the fact that he had come all the way out and I accepted the order. I'm extremely disappointed with the service. We order frequently from that nandos. To make matters worse they keep you on hold for ages and calls are dropped just when you think you're next to be answered. Very frustrating. Yesterday's tardiness though was the last straw and felt I must complain. The least they could've done is say the order will take an hour to arrive.
