In Denmark, companies are required to clearly and visibly state things such as total price - if they fail to do so, the "contract" is invalid.

Something approximately the same as that is true across the EU under the recent changes to the consumer protection rules.

On your other points, I'll just mention that this subthread was originally about whether accepting e-mail as a cancellation method was appropriate, not so much the original topic of trying to force people to call as an aggressive way to deter cancellation. It seems we all agree that making it excessively difficult for someone to cancel when they're entitled to is scummy behaviour, and I imagine the law in many places would take a similar view.
