I have no connection to any of the teams involved, but if you have problems getting this resolved, please send me a mail (my HN name @google.com) and I'll make it right.
And if it turns out that there's a pattern of a _lot_ of developers who all recently signed up for first-time Google Play Developer accounts just to monetize Chrome apps, I'd be maybe a little surprised, but more than happy to have helped identify an unexpected trend.
I'd also be curious what happens if people ask the normal channels for the refund, of course.
