It looks as if an outfit called Elite Club Management (they also manage Elite Club Casino) in Curacao are the people either operating or re-selling Liquid Club on. The
VP Business is a guy called Derek Purvis (dpurvis@eliteclubmanagement.com) who may be a useful channel to get this resolved if the casino is ignoring you.
It's powered by Chartwell, who will be useless as a complaint avenue due to their totally hands-off policies.
