Complaints
"It is always possible that something does not go quite as planned. We recommend that you first make complaints known to us by sending an email to info@happinesz.com. If this does not lead to a solution, it is possible to resolve your dispute and to register for mediation via Stichting WebwinkelKeur via https://www.webwinkelkeur.nl/kennisbank/consumenten/geschil
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 handled elsewhere, you are free to file your complaint via the European Union platform.
