Mango Canceled My Order

I recently bought a coat from the Mango website and got a message that it had been shipped. But five days later, I got a notice that the order couldn't be filled because the item was out of stock. The email said that, depending on how I paid the first time, I would get my money back. I was upset by this dishonest act, especially since the coat was still listed as available on the website. Even more proof, I took a screenshot. When I called the store, they told me that the coat was available in a few other places. If I don't get the product, I'll have to file a complaint with the Consumer Rights Authority, because what you're doing is against the law.
