"The cooperation was based on partnership and uncomplicated, even short-term agreements were possible without any problems, the direct line was always there. We liked the mixture of a strong customer and service orientation on the one hand, but also the courage to give us well-founded recommendations, very much. atac was also a great help when it came to image selection. We have experienced Markus Kalischek and Daniel Schneider as very committed, reliable partners whom we can recommend without reservation."
