This step is free on your town hall's or region's online office in Spain; you do not need DocMuse for it. For a consumer who already complained to the company and got no reply or no solution: a written complaint to the municipal consumer office (OMIC) or the regional consumer service asking for mediation and, if you choose, consumer arbitration. File it at the office, at any Spanish public registry or at a Correos post office as «correo administrativo». In regions with a co-official language the office must also accept it in that language. In Spanish.

Common questions
- Must I complain to the company before going to a Spanish consumer office, and what is the hoja de reclamaciones?
- Yes: the consumer office asks you to have complained to the company first and to attach its answer, if any. In a shop or premises, the free route is the hoja de quejas y reclamaciones, a complaint form of your Spanish region that the business must hand you on the spot; the business has a period to reply (ten working days in Andalusia, for example) and, if it does not, you take your copy to the OMIC. If you bought online or the business refused the form, a written complaint will do, such as the guarantee letter or the formal demand in this catalogue. The Spanish associations OCU and FACUA publish free model letters.
- Where and how do I file this complaint with a consumer office in Spain?
- With the OMIC of your town or, if there is none, your region's consumer service. You can hand it in at the office, at any public registry office of any Spanish administration, at Correos as «correo administrativo» (in an open envelope, so that your copy is stamped) or on the free online office. Keep the receipt with the date. The office passes the complaint to the company and mediates to reach an agreement; it does not impose a solution. In Catalonia, Valencia, the Balearic Islands, Galicia, the Basque Country and Navarre the office must also accept it in the co-official language.
- What is consumer arbitration in Spain, and what does asking for it mean?
- It is a free procedure before the Consumer Arbitration Board (Junta Arbitral de Consumo), as a rule the one where you live (Spanish Royal Decree 713/2024). A company that has joined the consumer arbitration system must accept it; one that has not may accept it or not. The award binds both sides and closes the courts to you for that same dispute. A request is rejected if more than one year has passed since your complaint to the company, and cases involving poisoning, injury or signs of a crime cannot go to arbitration. If you only want mediation, choose that option.

Send it by burofax with certified content, which proves the date from which the operator may no longer bill; you can also use any channel the operator offers. In Spanish.

If the airline does not answer within a month or refuses, a complaint to AESA, Spain's aviation safety agency, is free and its decision binds the airline. Send it by burofax or through the airline's complaint form. In Spanish.
