@Jstutz Hi there and welcome to the forum.
Very sad to hear your account got hacked and money stolen mate, but many others have experienced similar incidents at various casinos too, so you're not the only one.
I really don't know how to resolve a hacked account case, simply because it is so hard to show solid proof that it wasn't done by you on purpose, or that someone else got hold of your account and misused it.
Hope someone here can give better advice for you mate.
