If you have any difficulty completing the questionnaire, please contact us so that we can help you. You can contact our CBS Contactcenter by email. When doing so, please state which questionnaire you are completing, and provide your correspondence number and a telephone number where we can reach you. We will then get in touch. If you need urgent advice on completing the questionnaire, for example because the final submission date is looming, you can of course also contact us by telephone (see the contact details of CBS Contactcenter).
