One number for all your questions – a new telephone system for our customer service team

Date 15/09/2026

As of today, you can contact our customer service team regarding any subject via the central telephone number: +4930 8903 50 50

Our new telephone system will direct you to the appropriate member of our customer service team via keypad.

The old numbers will remain active for a limited transitional period, but calls will be routed to the central telephone number.

With this change, we aim to make it even easier and more efficient to contact us and be directed to the right person in future.
