Defy agent that don't care about clients

An agent will contact you by Friday, 23 Dec 2022 to attend to Defy service call no. ***. Please contact *** if not convenient. Same agent i had problems with in the beginning of the year February. He came yesterday, we arranged for today 13:00pm he doesn't answer the phone neither did he come to my house. Same problem with my double door fridge its not cooling/freezing what do he care but it's his job? I arrange to come home early just to find that i waisted my leave day to someone with a i don't care attitude. Im so fed up with Defy agents thinking they doing you a favour but it's under warrantee this confirmed to switch to other brands instead
