That sucks, you should have checked first what you're sending from here and there. But, I've seen this case in some casinos and exchanges when a user has deposited a wrong crypto to another address. Some were able to fully recover it but it comes with a fee from that platform itself. I have no idea if this has happened in the past with bc.game but I guess it did. Since you've already contacted them through email, how long and since when did you sent them that email and query? It takes time so, please be patient and wait until one of their reps reply to you and you've already posted here, for sure a rep will see your post but you have to add additional info like your txid or userid for them to check it.
