We advise you to first report complaints to us by sending an e-mail to [email protected]. If this does not lead to a solution, then it is possible to register your dispute for mediation via Stichting WebwinkelKeur https://www.webwinkelkeur.nl/kennisbank/consumenten/geschil/dispute/ .
It is also possible for EU consumers to register complaints via the ODR platform of the European Commission. The ODR platform is available at http://ec.europa.eu/odr
