From what I see they won't look into your case anymore, this becomes more confirmed because OP has been on the forum and hasn't responded to your complaints
You are right that BC.Game's representative is actively with log in but did not make any reply in Bitcointalk recent weeks. They no longer reply on any accusation includes this case. I can not know they are right and accusations against them are valid or not but with their latest activities, at least they no longer care about those cases. Maybe in their vision, they already considered those cases as closed.
I hope you forget about them, so you can at least rest, wasting your time with this casino will not solve your case, for them the case is closed and they will not go back on the decisions they make.
I see the user has habit to try using many casinos and after a while, with some withdrawals, he got troubles and not all cases he received all money back. I don't know why he would prefer to take so much risk this way. If he has good gambling skills, he can win on big and trusted casinos and will not have withdrawal problems.
