Horrible dilivery guy. Missleading phone calls

Our pizza was about an hour and a half late and when it does finally arrive we ask the dilivery guy why is it late? It's 22:20 now and the slip says 18:41!!!!! He says no I only got the pizza 5 mins ago and we ask him how come because we have been calling in, several times, to check our order and they said it had left 40 mins after we made it. He says no everybody protectstheir job and that it takes a while to to get from shop to home, I tell him he is lying because it takes, maximum 20 minutes to get from pinecrest to Ashley! He starts shouting at us and we tell him to stop shouting, we are all adults and we can have this conversation in a mature manner. The man proceeds to shout saying no everybody is just protecting their jobs, I only got the order now. And we were like ok fine but stop shouttimg at us. The man is busy demanding the pizza back and all that, talking to my sister in a very ill manner, I tell him to bring down his tone!!! He grabs the pizza and I tell him this is not how you speak to customers !! And we will be laying a complaint. After he left, we try call them again to tell them about the encounter, they didn't pick up...
