Out-of-court dispute resolution
The EU Commission provides an online platform for dispute resolution (“OS platform”) under the link

If the customer is a consumer resident in the European Union, there is the possibility of using this platform for the out-of-court settlement of disputes about contractual obligations from online sales contracts.

We are obliged to inform you about the existence of this OS platform.

We try to resolve any disagreements about contracts concluded with our customers amicably through our customer service. In addition, we are not obliged to participate in a dispute settlement procedure by the consumer arbitration board and are generally not prepared to do so.
