Misleading Defy warranty claim in supplier manual

I have been a big Defy supporter over past years. Friday evening 6 December I became aware that the freezer of my double door Defy FR DFF436 F740 bought on 27 Jan 2021 was not freezing anymore. Saturday morning I took all actions as described in the Defy manual, but nothing helped. To my surprise I noticed in the manual that the unit had a 5-year warrantee. I contacted the retailer Home Hyper City, mentioning the warranty and they said they would come back to me. I got no response until I called them again on Monday, when they said I should contact Defy on ***, which I in fact already contacted via whatsapp on Saturday. The response I got from Defy on Saturday was that they operate only 08h00 to 16h30 Mon to Friday, so I waited. I waited because according to the manual, the unit was still under warranty. During Monday morning I had a lengthy discussion with Defy via whatsapp. Defy insisted that the warranty is 3 years only, while my Defy manual clearly specifies the warranty is 5 years. Defy failed to convince me that my Defy manual was not valid, and in the end I gave up out of frustration, still convinced that the Defy manual warranty should be honoured. My problem is that due to Defy's 5 year warranty certificate in the manual, I waited for two days for repair under warranty, and lost a portion of frozen food waiting, despite using precautionary dry-ice. If the manual was clear, I could have responded quicker by getting private repair services sooner. The fridge/freezer is up and running thanks to a helpful and responsive repair service, RFF Appliance Repair (not Defy) after replacing a burnt-out freezer circulating fan.
