You should have moved the coins out. Now they're reverting the trades because the alternative is accepting liability for their awful security (which is probably, well, still awful). Bitcoin trading is the wild west, if you behave like Jesus Christ you're just going to get nothing out of it. What I mean is that in such a risky business you shouldn't feel guilty ripping people off, they had it coming after all, it was their choice. UNLESS, of course, you're having second thoughts because you're related to the hacking and backed off when you got nervous, seeing how far the prices went down and how the massive buy order did manage to go through... just a possibility, no offense. The fact that you gave them your id and didn't behave like a shady guy is irrelevant as long as it's impossible that you be proven guilty, in fact that's exactly how the clever shady guy should be behaving... like "not guilty", because money is usually traced in the end, and you want to look like a saint when that happens. So, their position about contacting you is perfectly reasonable and natural; to them you might be related to the hackers anyway and anything they say to you (nothing they could say would be good- a conversation with them would be full of unanswered questions) is likely to end up in a public forum. Not good pr.
