An important board was recently closed. The admin no longer works for this company.

Earlier this week, I received this message from a board I rely upon:

[Trello board] is closed. You’re a member of this board, but only board admins are able to reopen it. Please contact support for assistance.

My former colleague no longer has access to the company account. What can I do to restore my access?
