The European Union provides an online platform for dispute resolution available for the settlement of disputes between professional vendors and non-commercial residents of the European Union (consumers), in the context of paid sales and service contracts. Participation in the online mediation program is voluntary. Also, if Lesson Nine does not participate in this program, our Customer Service department will continue to competently provide help to users: support@babbel.com. The online platform for dispute resolution can be found at hier.
