I believe the invoice is not correct. How can I check whether my invoice is correct or request a change?
For invoices regarding events, please use our Online Portal:
- You can request a change in the area My invoices.
- Select the event in question.
- Enter the reason for the change and upload any evidence you may have.
- Just click on submit form, that’s it!
To clarify: Invoices for these types of use are not yet stored in the Online Portal.
