The case wasn't properly fitted and yes, it does happen a lot. Have you loosened the strings? That can help sometimes...
Anyway, I don't know how to help - the only thing I can think of is letting you know about a luthier in Poland (my uncle uses him to fix his vintage Gibsons) and he is amazing. I don't know how much exactly a fix like that costs in the UK, but it would save you a lot of money if you want to ship it to Poland (seeing that you're in Hampshire), get it done and ship it back. And you won't be able to tell that it was broken unless you really look for it.
PM me if you think that is something you would like to do. I ship guitars/amps over pretty much every week.
Once again, sorry about what happened. Good thing it wasn't 2 grand guitar...
