Where did you order?
If someone shipped a damaged package like that (waterdamage) I would return it to sender and ask for a new copy of the game. Would not tolerate this.
You could try out facebook, twitter etc.
In germany they would need an "Impressum" stating where the firma sits and how to contact them.
Still the company has to be registered somewhere so I would try to find out and get a phone-number or adress.
I funded the kickstarter of the second edition.
Next time I will only buy products from actual shops. They appear to be too amateur to the after sale service and with a game with that many pieces, this is crucial (or should be).
