You can change the personal data on a ticket via Name Change. In the confirmation email you received from Paylogic you will find a button with the text: 'Manage order'. You will then see an overview of your purchased tickets. Click on 'More actions' at the top right and then on 'Name Change'.

Note: Name Change is not a safe way to exchange money and tickets between strangers. So don't be tempted to use this anyway through Marketplace, for example. There is no deadline to change a name.
