Bought a Hisense 55N6 from goodguys ebay 20% off sale - ordered Friday with delivery.
Got an email on the weekend that they had no stock and was on backorder (money was taken on checkout).
Called them today as I needed it for a gift, cant say when it will be in but will refund and can take another week for funds to show up.
I questioned them about taking money for something they dont have in stock but the 'system' caused the issue as I ordered the same time as someone who took the last one.
Obviously a lie as the listing is still here with estimated delivery of a few days:

I had the same thing with an aircon unit before Christmas. They were good about it, asked me if I wanted to swap for something in stock but I chose to wait as the sale was over so I didn't want to pay full price. They said I could cancel the order at any time if I wanted to.
