Hey, no idea if you still expect some kind of response from them or just didn't bother again since then, but I thought Why not share my amazing story too?
Usual things, got banned in the middle of the game, no warning or idea why, no timer to show me if I'll ever get it back, was my first time as well, so I was so pleasantly surprised, and of course, no way to contact them.
I didn't even get the blue screen you had, it was like the SUBMIT button was fake, no reaction or anything loading, just me clicking a random spot on screen. But after a couple of days, I thought Why not try internet edge? And voila, it worked! I even got a half serious captcha test, I just marked me as human (and denying my alien father on the way, sorry pops), and after that I got a message telling me - We appreciate your patience as we are experiencing a higher than usual volume of tickets.
That was also confirmed by an automated mail I got soon after, so hopefully they will be able to resolve this Nightmare before Christmas.
Hope I helped.
