I’m an unhappy customer

Office london does not even deserve a single star, they made me buy sneakers only for them to tell me two days after that they have decided to cancel my order due to unavailability of stock, tell me whose problem is that? Because when I placed an order and paid the sneakers are not there now i have to wait for ten days max to get my money back, what if I want to use that money for something else. They are *********** and I’m never wishing to do business with them ever again.
