First of all it is very nice of you to help a player.
I think there is really not much you can do other than send an email to [email protected] / [email protected] or try Nicolas at gamblingwages.com. Live support will not handle this I am sure.
Besides that you are promoting welfare (this program will not pay you a dime). You have been tricked to promote this casino and will not get a commission at all (the statspage has been deleted and you can not check your “possible” earnings).
So delete it.
I hope you will get the cabbage for you player.
