Domino's Pizza — non delivery of product

I ordered dominos pizza which they did not deliver within 30min.. Inspite of service guarantee. When i called back after 40. Min. They tell me order is not placed. I raised a complain on dominos facebook. Page. I got a call asking for evidence. Joker who called wanted recording of the call.. What a monumental piece of crap he was. Whu would i record a call when placing order.. Absolutely pathetic.. A. They don't deliver and post non delivery he is asking for evidence that i placed an order. As if i don't have anything better to do.
