If you have a question specific to event information (Event Date/Times, location, access, requirements etc.), you can get directly in contact with the event organiser via the Billetto event page. Alternatively if you have purchased a ticket in the ticket confirmation email you will see their contact address.
A link to contacting the event organiser can be found just beneath the main picture on the event page itself.
If you have already purchased a ticket, you can also find the event organiser's email address in your confirmation email.
