The support isn't really getting back to me, although I do have a case #. They actually emailed me a recommended thing to try that seriously had nothing to do with the error I was getting (WOW).
This is pretty typical. I had a support ticket back in August (when things were much calmer), and they sent 3 unrelated boilerplate answers at first. I kept pushing to get a real human being. When I finally got one, he misunderstood my issue and gave me another boilerplate answer. I imagine things are much worse now that 100k new users a day are signing up.
It's pretty annoying that they require webcam or mobile camera for this. Built-in webcams never provide good enough quality for verification. I think this is the most typical problem, and something I struggled with a few months back. If you haven't used the mobile app with your smartphone camera to verify ID, I suggest doing so.
