Livro de Reclamações - Complaints Book / Portugal
All portuguese suppliers of goods or services that carry out a professional activity in a fixed or permanent establishment in contact with the public (customers) are required to have a Complaints Book. If you feel you have been damaged/affected regarding the good or service you have purchased, you have the right to submit a complaint by using this book.
Once the complaint form has been filled out, the good/service supplier (or employee of the establishment) must separate both the original and duplicate complaint form from this book. The 2nd copy must be handed over immediately to the complainant, and the original must be sent within 10 days by the good/service supplier to the competent authority (Regulator). The 3rd copy must remain in the complaints book.
The supplier of goods or services is now under the obligation to display, in a clearly visible place and in easily legible lettering, the indication that it is available for its customers the complaints book and the identification of the competent authority that will examine the complaints:
"Este Estabelecimento dispõe de Livro de Reclamações"
("This Shop/Restaurant/.... has a Complaints Book").
If you write in any other language than Portuguese it has to be well readable in order to be able to translate it.
