A username cannot be edited by the user or the main user after it has been created.
If a username needs to be edited afterwards, please contact our customer service,
who can make the necessary changes.
All username change requests are subject to a charge. Updating the username is free
of charge only if the user’s last name has changed, and the user wishes to update
their existing username.
The charge for any changes made to usernames is 30 € + VAT (1 to 4 usernames).
Additional usernames on the same request cost 8 € each.
