If you haven’t had a reply from the event organisers this may be that your refund request has been declined. If this is the case, you will need to pass on your tickets privately to ensure that you don't lose out on the money spent.
Due to the uncertainty of when events can take place again, please keep an eye out on the status of your event here. If the event is marked as cancelled or postponed once more you may be given another refund opportunity.
