Leon's Furniture review: fridge

I bought a new fridge from Leon's in Aug, 2019, floor model. It broke 3 months later. I Called manufacturer who said it was older than 5 years old already. Leon's sold me a 5 year old fridge as if it was new. They won't take it back. I spoke to 3 different sales people who said, "They would never sell that" . "Our floor models are only a few months old" . "a fridge only lasts 5 years"
I want a full refund. If I wanted an old fridge I would have gone Kijiji.
