So, let me try to nudge them again?
You are doing a great work here even though you aren't going to get any benefits from it. No-one would forbid you to do that. But I can already see the frustration from OP's side. And it is reasonable.
And, given withdrawing SC itself is not possible and there were no SC option on the drop-down menu, can you please try to select other currency, see if the withdrawal is now possible and the "redeemable amount" will now shows and indicate you can withdraw?
There are only two displayed currencies on BCgame.us, those are SC and GD. The SC works in the same way like the dollar value in some other casinos (1 SC = 1 USD). They accept deposits in crypto and automatically convert it into SC and credit it to user account. It is similar to Duelbits or Rollbit deposit and withdrawal system. Those casinos just convert our deposits in $ value. At BCgame.us SC stands for the $. I hope it is clear to you now.
OP is saying that his SC balance is still null. Actually, his withdrawal was cancelled by the system, but the funds haven't been credited back to his account in SC. It is stuck somewhere on the system and only showing the balance in LTC currency when OP is on the deposit page.
