Let tokens expire in Mail - Any way to restore?

I'm an idiot and trusted a source I googled that suggested WoW tokens in the mail wouldn't expire. "Mail containing WoW Tokens do not expire." It also appeared this way as they didn't have the usual red X mail going to be deleted will have. I was going to leave them there to save bag space and of course they expired.

I tried the 'Recover sent, deleted, or expired mail' page and these items were marked as unable to be returned. I noticed "You can only recover the mail items listed below—contacting a Game Master will not give you access to mail missing from this list." at the top.

Am I truly just out 9 WoW tokens? Has anyone had a similar experience and success retrieving items? If nothing else maybe someone else considering this idea will see this and not make the same mistake.
