It is crucial to ensure that recipients of the service can communicate effectively with providers of intermediary services, including in cases of complaints or requests for information. For this purpose, providers of intermediary services should be directly and easily reachable by electronic means, such as email, and, for providers of online platforms, also by telephone and, where appropriate, for larger providers, online interfaces such as web forms or chat bots or an online help desk, that are available to the recipients of the service in an easily accessible place. Providers should also offer such communication channels in a language that is easily understandable to the majority of the recipients of the service of the Member State or Member States where the service is offered.
