You didn't get it why did he want his account? Because he invested in Ad Campaigns and he brought players to BC Game for affiliate commission. He already has 113 Affiliates which is not a bad number of players. He spends a lot of money on an ad campaign. I had a conversation with him. He looks helpless. He said He don't want bonus balance or free spin. Simply he wants his account so that he can claim commission from the affiliate page.
Don't you think he is legit from his side? Think of yourself in his place. If he wants those deposit bonuses he could unlock them in that one month. But he didn't. He was just trying a Free Spin every day to play. And bringing players with ad campaign so that he can get some commission from them and it's something like passive income? So he focused on that. I hope you understand why he wants his account.
I would suggest contacting Efialtis who is the owner of BTCGOSU. He has contacts with the bc.game admins and maybe he can mediate if he believes the user has a fair case against them. Send a PM to him explaining the full case in all details.
