I just fell afoul of their recent bug to the tune of them closing out a profitable margin trade by taking away 0.9 BTC (actually 31 XMR from my balance) that I didn't owe them.

Has anyone had anything similar happen and get their coins back?

5 days and no update. It's a disgrace. I have reported them to FinCen. Was considering going to their offices but read on other threads that's fruitless as the offices don't exist.
