It can always happen that something does not quite go as planned. We advise you to first report complaints to us by emailing info@wbtuning.nl
If this does not lead to a solution, it is possible to submit your dispute for mediation via Stichting WebwinkelKeur via https://www.webwinkelkeur.nl/kennisbank/consumenten/geschil. As of February 15, 2016, it is also possible for consumers in the EU to report complaints via the European Commission's ODR platform. This ODR platform can be found at http://ec.europa.eu/odr. If your complaint is not already being processed elsewhere then you are free to file your complaint via the European Union platform.
