Worst customer service ever

Today I got to personally experience the worst customer service ever. I placed an online order with Debonairs Pizza Southgate at 16h39. Just before 19h00 a delivery guy arrived with a wrong order. He then went back saying that he swopped orders and had given mine to someone a street away. We expected him to come back with the correct order within minutes but hey we waited. Moments after we decided to lay a complaint with the call center, in no time someone by the name of Witness called back saying he was the manager at the southgate branch. I explained my story to him and he confirmed that he was sending someone right away with the correct order. After an hour at about 20h20 we then decided to go to the store because we still had not received the food. We wanted to cancel the order because it had already taken 3 hours since we placed the order. Mind you we ordered because we were hungry and needed food. We arrived at the store at 20h28,requested the manager and we got the worst disappointment ever from someone in his position. At first he could check the time the order was placed, he didn't show any sympathy to us and he didn't even bother to apologize for delivering such bad customer service. We request refund, he gave us the money and we left. No apology whatsoever. I wonder where Debonairs got such a person to be on the front line when he doesn't know nor understand what customer service is. I will never set my foot in denote southgate again. The delivery guy then arrived at 20h55 with what he called correct order but we turned him away. I work for customer see my self and I didn't believe something like this exists, but Debonairs gave me a lifetime experience that I will never forget.
