Member States shall ensure that transparent, simple and inexpensive procedures are made available by all postal service providers for dealing with postal users' complaints, particularly in cases involving loss, theft, damage or non-compliance with service quality standards (including procedures for determining where responsibility lies in cases where more than one operator is involved), without prejudice to relevant international and national provisions on compensation schemes.

Member States shall adopt measures to ensure that the procedures referred to in the first subparagraph enable disputes to be settled fairly and promptly with provision, where warranted, for a system of reimbursement and/or compensation.

Member States shall also encourage the development of independent out-of-court schemes for the resolution of disputes between postal service providers and users.

Without prejudice to other possibilities of appeal or means of redress under national and Community legislation, Member States shall ensure that users, acting individually or, where permitted by national law, jointly with organisations representing the interests of users and/or consumers, may bring before the competent national authority cases where users' complaints to undertakings providing postal services within the scope of the universal service have not been satisfactorily resolved.

In accordance with Article 16, Member States shall ensure that the universal service providers and, wherever appropriate, undertakings providing services within the scope of the universal service, publish, together with the annual report on the monitoring of their performance, information on the number of complaints and the manner in which they have been dealt with.
