Everything alright with your preorder?
Is your preorder not marked as paid, but you transferred the money last week or earlier? Mail us right now and be sure to provide transaction metadata (name of account holder, account number, sort code). We may not be able to help you with your failed preorder on site, so please make sure you have your tickets before going to the cash desk (or be prepared to buy a ticket on site).
If you’re planning to buy a congress ticket on site, please make sure you bring enough cash as we cannot accept any other kind of payment.
