Here’s what consumers have asked with answers from Loot Crate staff and previous consumers.
If you look at the good reviews, they are from 2014. This company has gone way down since then. Now they just take your money and never ship. I wouldn't be surprised if they go out of business soon.
Just accept the loss. It will take weeks to even get a response forom customer service and you will end up with an excuse, expense of returning what you have and will either 1) get two more wrong items after several more weeks, 2) never receive the exchange items at all or 3) get a refund if they are threatened with a PayPal claim.
