If you have a complaint about a postal service you can submit it to the provider of the postal service in question. In case of the press, editors usually provide for the possibility on their own websites to report in a few clicks delivery problems regarding your subscription.
If the dispute cannot be resolved, you can turn to the Ombudsman Services for the Postal Sector, an independent federal service that mediates in disputes.
The ombudsman services treat problems with national and international shipments for all postal companies. The service is free, but first you must have tried to solve the problem together with the company itself. If mediation fails, either party can consider arbitration, a legal procedure or mediation (ADR).
You can file a complaint on the website of the ombudsman services, by post or by e-mail. For more information about the procedure and terms and conditions, please go to the website ombudsmanposte.be.
