To safeguard our customers and simultaneously ensure the constant improvement of our services, ATM offers various means through which customers can contact us to make complaints or provide suggestions: an online form, ATM Infoline, and by post.

The response times are 10 days. The complaints response process forms part of our quality management system, which conforms to UNI EN ISO 9001, 14001 and 13816 standards and is subject to periodic evaluation. All data supplied by customers are processed in accordance with EU Regulation 679/2016.
