The nature of the relationship between providers of online intermediation services and business users might also lead to situations in which business users often have limited possibilities to seek redress where unilateral actions of the providers of those services lead to a dispute. In many cases, those providers do not offer accessible and effective internal complaint-handling systems. Existing alternative out-of-court dispute settlement mechanisms can also be ineffective for a variety of reasons, including a lack of specialised mediators and business users’ fear of retaliation.
