What does the american law say about that?
If the law says you must be able to cancel and get a refund if it takes longer than twice the time they say when you order, they have to give a refund, even if it says something else in their policy because the law is more important.
I'm not sure what law they must follow for orders in other countries, for example for me. The dutch law because I order it from within the Netherlands, or the american law because they are an american company.
