With all due respect, and I am not aiming this at you personally or trying to start a witch hunt, but an "update" full of half truths and vague corporate deflection, that basically boils down to "We won't tell you anything yet" is not really a satisfactory update.
"We were saddened to learn that some of the team we were working with to deliver RuneFest are no longer with the company." It was already public knowledge that it was not just "some" redundancy, and that in fact the company was collapsing before this news post was made, this is a purposefully vague and disingenuous statement that is worded specifically for damage control, not honesty and transparency.
And while the news post promises every opportunity is being explored, there is absolutely zero context into what these opportunities are, this sentence could be talking about new venues and staffing and other avenues to ensure the event occurs, or it could be talking about how Jagex will handle the cancellation of the event and any subsequent returning of peoples funds. Without context, without honesty and transparency, it means nothing.
I completely understand this catastrophic failure is not Jagex's fault. Jagex are also a very unfortunate victim in this scenario, but it was ultimately Jagex's decision to partner with this company, while it will undoubtedly cause Jagex issues, those issues should not be being passed onto the 2000+ customers that are also directly affected.
Ultimately there are only two reasons for a lack of communication and transparency here, to protect shareholder investments from market fluctuations due to negative press, and so that Jagex can hold onto whatever revenue was collected as long as possible.
Your customers are not stupid, they know full well that "we will have more information for you as soon as possible" and "we are doing everything we can for you" actually means "although we have information we could share, we are instead going to be controlling the flow of information for damage mitigation" and "we are doing everything we can to minimise our losses".
I am highly confident that internally a number of decisions have already been made, and whether those decisions involve date and venue changes, or a complete cancellation, Jagex needs to make people aware, like now.
People have invested thousands into this event, it isn't just about ticket prices, there are flights, accommodation, time off work, your fans have already invested time, effort and money into this, and even if the event goes forward but at a different time or place, we are rapidly approaching a time where even people with tickets will simply not have enough notice to change those plans or investments and will not be able to attend anyway.
