SAMSUNG WARRANTY SHAM!!!!

Bought a SAMSUNG microwave from MAKRO woodmead on 06.12.2018, this microwave decided to stop working last sunday so on monday we loaded it and took it to Makro, because of a dent on the top side of the microwave we were shown the door as they do not fix anything with a dent or a scratch as it voids your warranty . This microwave has a ten year warranty on it - according to SAMSUNG the warranty is for the casing only but the rest of the machine has a two year warranty but because I dropped a wooden chopping block on the top and dented it the warranty/guarantee is void!! How does that work I mean you save in todays economy to buy decent items and then get treated like trash if there is a problem with the bought item as the manger at Makro was not friendly at all. I left a query on the samsung webpage and they came back with the housing story and then I did a live chat with a lady and all she could say was sorry - how is this for customer service??? Samsung sucks big time !!!!!!!
