To consumer protection laws in Denmark state that, you cannot cancel for a periode in the past. If you've prepaid they can keep payment for "30 days end of month", but anything beyond that must be returned. For monthly payment, you must be able to cancel up until the next payment is due. It doesn't matter if the service is used or not.

Out of curiosity, are there any limitations on those Danish rules? For example, suppose someone is running subscription access to a magazine at $5/month, but wants to offer a discount if customers sign up for a whole year to say $45. This sort of promotion isn't unusual, and it's potentially beneficial to both the magazine and the reader, but from your description it wouldn't be viable under Danish law.
