Murale à peindre tropical laisse

Thought this was beautiful when I received it. Spent an afternoon putting it up and loved it, but by the next morning it was almost all peeling off! I bought wallpaper seam glue to try and fix it, but now some of the edges don’t even come together anymore like it shrunk. All edges overlapped when first installed now the pink wall is showing. I am so disappointed that I spent $500 on this wall and this is how it turned out!
