I'm dealing with the same thing. Not the driving 12 hours thing, but bought tickets to this game and never received them. Currently on hold with Customer Service for 55 minutes and counting.
The guy helped me get our tickets. We had to log into our ticketmaster account to do it.
the website he gave me is:
Then, he had me go into the manage my events tab.
He wanted me to download the ticketmaster app on my phone, but before I did, I got the email to accept the tickets.
I hope this works for you! GO AVS haha
Yippee! I'm so glad I could help. I feel bad you drove so far and almost didn't get to go to the game. Even if you are a Blues fan. hahahaha How about you win one game, but not in our house!!! Have loads of fun!
