So, did you can access the account with that address or not? or just some speculation you ask them to look the account with that address and they send full information like Email, ETC. I guess you also need to provide your log in on "CoinRoyale" with your email + show them the deposit address is belong to you with some video capture I guess. The  only problem always how to verify you are not using that fund for bets due to this problem have a gap 4 years and almost some casino not really save at all history for a long gap time. I believe you still can SS the picture for number 9 as well.

If, you can provide all those things make the scam assumption against them because there is no any information at all on FAQ and T&C about the rules any balance more than 1 years will be remove.

Use them FAQ and T&C for the response that.
