In order to enable business users, including those whose use of the relevant online intermediation services might have been restricted, suspended or terminated, to have access to immediate, suitable and effective possibilities of redress, providers of online intermediation services should provide for an internal complaint-handling system. That internal complaint-handling system should be based on principles of transparency and equal treatment applied to equivalent situations, aimed at ensuring that a significant proportion of complaints can be solved bilaterally by the provider of online intermediation services and the relevant business user in a reasonable period of time. The providers of online intermediation services might maintain in force during the duration of the complaint the decision that they have taken. Any attempt to reach an agreement through the internal complaint handling-process does not affect the rights of providers of online intermediation services or business users to initiate judicial proceedings at any time during or after the internal complaint-handling process. In addition, providers of online intermediation services should publish and, at least annually, verify information on the functioning and effectiveness of their internal complaint-handling system to help business users to understand the main types of issues that can arise in the context of the provision of different online intermediation services and the possibility of reaching a quick and effective bilateral resolution.
