Deleting and cancelling are both handled from one control on the event's edit form. The control is labelled Cancel event — there is no separate "Delete event" button on the form, which is why it can look like the option is missing.

1. Go to Events, click the three dots on the event, and select Edit event.
2. Scroll to the bottom of the form and click Cancel event.
3. What you're offered next depends on the event:
   • No brands have applied yet — the dialog is titled Delete event? and you can delete it yourself right there. This is permanent.
   • Brands have applied — you'll be offered to cancel the event, with a box to give a reason.
   • A partnership is blocking it — the dialog lists the blocking partnerships and lets you send the request to support from that screen.

If that flow doesn't get you there, contact support with the event name. Support will reply by email within 24–48 hours. Support can only delete events that have no pending or completed brand partnerships.
