Informed that there is no stock 10 days after I ordered and paid

I ordered and paid for a fridge that was on special, payment made on 19 November 2021, and order confirmed. The Avo team contacted me on 29 November 2021, to inform me that the fridge is no longer in stock with their supplier. This means I'd have to wait another 10 days. What upsets me the most, is that they inform me of this stock shortage after BlackFriday deals have come and gone, so I can't even get the same product on special anywhere else now. I'm heavily disappointed, and wish that I had ordered through TakeAlot, who have proven themselves over and over. I went for the deal on Avo due to saving on delivery fee - but boy was that a bad decision.
