It can always happen that something doesn't go quite as planned. We recommend that you first make improvements/complaints known to us by sending an email to firstname.lastname@example.org. If this does not lead to a solution, it is possible to register your dispute for mediation via the ODR platform of the European Commission. This ODR platform can be found at http://ec.europa.eu/odr. If your complaint is not yet being processed elsewhere, you are free to deposit your complaint via the platform of the European Union.
