Didn't I tell you that "the personal stats could not tell me anything, or let me send you the details on it because I meet the same problem again recently though the problem is not always happened"?
Which is provably false. Your personal stats show it as a loss under "MULTIPLY BTC WINNINGS".
I also told you that "I have also sent a contact form under FAQ section. It is about I lost 0.05 BTC (but I am not sure how about I lost).
And as I keep telling you as well it showing on your stats page you can then look at your roll history for the details of how you lost it. It isn't support's job to check your activity for you. Everything you do is shown on the relevant pages.
