I'll speak in generalities, and start by saying I'm not interested in complaining, sob stories, or trolls---just an honest question.
I worked support for an organization quite some time ago, and if the backlog of tickets got too big, we'd simply purge them, and assume if it's really important, people will contact us again.
I was wondering if Gree might be the same, and whether I should resubmit my issue if I don't get a response after say, a month, which seems plausible at this point.
