I believe there should be some guidance for posters. It is not about naming and shaming but such post should come with a bit more information so readers can assist such as manufacturer, shop etc. unless it’s spam shops and manufacturers act differently. Under 6 months even if it broke from reasonable use due to your fault I am sure it can be argued that it is a quality issue since fridges by design will be opened numerous times and by many people. If the shop is refusing write directly to manufacturer, I have had great experiences with that approach.
