After two years my Neff Microwave door yet again is causing problems. Now the product is out of warranty Neff don't want anything to do with it, unless you pay them. On the first visit last year (2023) the door dropped, the engineer under warranty added nuts to the self-tightening bolts/screws to stop them from loosening ....clearly wasn’t designed or manufactured this way.. He removed the whole unit, removed the cover and reinstalled the built in Microwave. Nothing mentioned about brackets, or out of tolerance etc. There was no leak test either! The glass panel recently cracked so had to purchase a new door, this new door doesn't align correctly so I contacted customer services who rejected the issue, claiming that no leak test has been undertaken and due to H & Safety they can't do anything. I’ve requested evidence of the previous test which i know the engineer never undertook and they can't provide confirmation, well isn't that a surprise. Finally, they agreed as a gesture of good will to send an engineer.....I recognised the engineer from previous visit but he denied knowing me....he then placed his I pad on my worktop and referred to notes from the previous visit....slightly odd if he has no recollection of a previous visit. This time he was totally dismissive of the issue and was blaming the kitchen installation, didn't mention that last time around! He was rude, obnoxious, and talking down on me and continued to argue and blame the kitchen installation all the kitchen units are flush and all doors align perfectly. The oven door, unfortunately has two issues the bottom left hand corner is not sitting flush, and the two brushed steel strips don't align perfect horizontally with the integrated oven below which looks unsightly particularly when you have paid thousands for what is supposed to be good brand. The engineer had a bad attitude didn't want to help, when I asked him to show me the brackets he believes are missing from the installation he refused and said refer to your installation manual, when i provided him with a copy, he refused to refer to the relevant page. He forgot that he reinstalled the microwave on his last visit! This kitchen inbuilt unit cannot be adjusted, the microwave slots into the recess opening. There is a L shaped side plate on the left hand side of the microwave which sits flush against the kitchen cupboard and is screwed directly on the microwave with pre-defined screw holes so you cannot adjust the microwave at all. The engineer walked out ignoring me when standing beside his car door taking photo of his reg…he drove off
