AEG Microwave warranty

I bought a microwave in 2020. Had problems with it in 2021. It couldn't be fix so they said I can return it and get a new microwave. Great good service. So I got a new microwave which gave the same fault a year after. Both faults was that the microwave don't want to warm the food. Now they tell me the warranty for the 2nd microwave is expired because it is on the 1st microwaves warranty. They inform me only now if I took a refund and then buy the new microwave then the new warranty would've kicked in. So nobody informed me about this, not AEG or House and home:( I feel it's a new microwave I got the 2nd time and all new microwaves have a new warranty. So please do your homework when buying a good microwave and also how the warranty work on faulty merchandise. I would like proof on my contract that this is how their warranty works. I got a mail from AEG to say they will not fix the microwave but this is just a review so that customers can see how unfair some retailers can be.

Peace.
