Weve used Crown several times for oversees shipping in 20ft or 40ft containers. Everything was meticulously packed and wrapped and everything arrived without any damage whatsoever. I believe insurance was automatically included in the quote but dont recall for sure.
In your case TO I would make mincemeat out of these morons. With all items smashed they are responsible for the damage and should be held accountable, insurance or not.
Good luck, so sorry this happened to you.
