Online dispute resolution
By a special regulation of the European Union, from 15 February 2016, it ispossible to resolve disputes related to online shopping throughout the EU via the ODR platform, which you can access here.
This means that if you encounter a problem during an online purchase within the EU (defective product, inability to replace the product, etc.) you can file your complaint in a faster and easier way at the link above.
The platform can be used by both consumers and traders, and can be filed in any of the 23 official EU languages.
