Works council tickets can be exchanged if you place a new order. The amount of the exchanged tickets will be deducted from the amount of the new order. A form, the order form and all invalid tickets must be returned to us by registered mail. Please note: If you purchase tickets via a web reseller or an Inter-company group of works councils, the latter must send us the request and not the final customer. The credit note will only be issued to the organisation that made the original financial transaction.
