They cancel orders when the price does not suit them, and lie telling the item is out of stock and then restock the item on the website! (hoping the customer will not notice)
I ordered two times the same item, same size, there was two items left in my size and each time my order was canceled telling me the item is out of stock whereas the two items left were restocked few minutes after the cancellation of the order
In reality, they canceled my order two times not because it was out of stock but because I used my 15% off bronze fidelity code on sale, and the price paid seems not sufficient enough for them… That's against their conditions, they have no right to cancel my order because they don't like the price I paid!
They are SCAMMERS! A disgusting practice, which I never experienced (after 15 years of ordering on luxury retailers) until I ordered on Farfetch… And I'm not the only one which report this practice, they do that regularly, you can see plenty of reviews about this matter.
