(10)To ensure that the complaints handling procedures are effective and meet their objective of a prompt, fair and consistent handling of complaints received from clients, it is of paramount importance to ensure that the relevant persons in charge of applying such procedures within the crypto-asset service provider are well aware and appropriately trained with regard to such procedures. Such communication and training should also contribute to effective policies and procedures and to ensure compliance with the requirement to employ personnel with the knowledge, skills and expertise necessary for the discharge of the responsibilities allocated to them, in accordance with Article 68(4) and (5) of Regulation (EU) 2023/1114. The training should be proportionate to the efficient handling of complaints and should not result in an excessive burden for crypto-asset service providers.
