Ask HN: Facebook blocked our Ayreon tribute band's page, how to contact staff?

I'm in a Dutch tribute band that performs the music of Arjen Lucassen (also Dutch), which I'm sure some people here might have heard of. We are frequently in touch with Arjen and have his full blessing to play his music, and have his written consent for using Ayreon in our name (Ayreon Project).

Now suddenly, in the weeks before live shows where ticket sales are critical, Facebook has blocked our page (https://www.facebook.com/ayreonproject) with as stated reason that we are impersonating someone fraudulently. We have submitted an appeal with no success, and now seemingly have no other recourse to take and our page is apparently scheduled to be fully deleted in 30 days.

We're pretty desperate to get our page back along with the, for us, significant amount of followers and history. If we could talk to an actual person we could explain that we have full permission and blessings to use the name Ayreon Project and provide any proof required.

Any advice on how to proceed here? It just doesn't seem fair.
