Without a doubt, the worst customer service I've ever experienced. These guys tried to hold MY MONEY hostage. It might not seem like it now, but these guys are going to be remembered in the same thought as Mt Gox. They're happy to take your money, but when you need assistance because their awful application doesn't work as expected (and it WILL happen), you're completely on your own.
Managed to get my money out by transferring Bitcoin out in time.
Avoid at all costs. YOU HAVE BEEN WARNED.
Finally, don't be fooled by their "support" on social media/reddit. They tell you to get in touch if you announce a problem publicly but when you do, they never get back to you. Publicly, it looks like support is happening. But it's not. I think they have one person working support. Seems all he's doing is scratching his balls.
Avoid at all costs.
