Is Xwin Casino legit? Any bad surprises?

Xwin Casino seems to be a pretty big name in Brazil, and I'd like to hear from people who actually played there, not just the happy first-week stories. The Curaçao licence is on the table, but what matters more to me is how things go when something breaks.

Lately I keep thinking about the usual traps: a withdrawal that sits pending for days, a bonus that gets cancelled after you've already wagered half of it, or a sudden request for extra documents right when you want to cash out. Those are the moments that show what a casino is really like…

So did anything like that happen to you on Xwin? And if it did, how was it sorted out: support replied fast, you had to push for it, or it never got fixed?
