I think it is better to move this in scam accusation and put all your proofs so that DTs can decide whether the cloudbet should be tag or not.

Anyway, there are many users complains here about this site and telling that this site is scam like the threads below.

and this one https://bitcointalk.org/index.php?topic=1755403.0 but this issue has been solved.

Beware on their TOS this is mostly the problem of most of the cloudbet players.

I also suggest you to try contacting them again from their official thread from here https://bitcointalk.org/index.php?topic=333552.5560
and let them know about your issue including your proofs(Maybe this time they will pay you winning bets).
