It is always possible that something does not go quite as planned. We recommend that you first report complaints to us by emailing info@kocosmo.com. If this doesn't lead to a solution, it is possible to register your complaint for mediation via Stichting WebwinkelKeur. From 15 February 2016, it is also possible for consumers in the EU to register complaints 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 dealt with elsewhere, you are free to file your complaint via the European Union platform.
