Anyone ever heard of the exchange lupebitex.com?

One of my coworkers found this exchange advertising higher selling prices than other exchanges. So he went ahead and signed up and sent all of his assets there, about $1600 worth. Now he has to pay $600 just to do a withdrawal, if he can even successfully process a withdrawal. He has tried messaging support, no response. I cannot find an email address or any means of contact, I cannot find any information about this exchange anywhere. I think my coworker has been scammed. Is there anything we can do about it?
