OK - I've got money lost at CRYptopia too. And I'm not happy about it.
But Grant Thorton is not a "bad reputation" company. It's a major global accounting services firm with a very good global reputation. While no one is happy, it takes years to settle a liquidation. Nothing you can do but wait.

Lesson learned - not your keys, not your coins. if you leave coins at an exchange, it's on you.
