Amazon support is excellent. I would contact them again and ask if they have received replacement discs from the manufacturer. They probably won't know the answer off hand, but they can get back to you.
That's what they did with me on Lost Horizon. The exchange went very smoothly.
I just checked Amazon, and the Blu-ray from Unversal Music is not for sale directly through them. Only through third-party sellers. That means it's on hold, although they don't have the usual statement on that pages saying so. However, it's an all-regions release.
