Unreliable & impossible to get hold of. They failed to show up with the Wayfair order. The only number that I could find was for the supply chain and they don't even answer that + I was left on hold for ages and charged 7p per minute for the pleasure. I called Wayfair and the guy even agreed that XDP are awful and he didn't know why they still use them... even Wayfair doesn't have a number that they can call. Just a terrible company that doesn't care at all about customers. God knows whats happened to my order now.
