I have seen lots of issue recently with cloudbet but to prove anything you better post some proofs to support your claim. And rather than posting here you can create scam accusation against them if you want, that may also help you to resolve your problem fast.
I have already stopped betting with them long time ago.
They refused to grant me access to my casino game history and i even discussed this with the ezugi casino support and they said only cloudbet can give me access to the game history, To be honest with you, i am even suspecting that ezugi, it seems they are working with those casinos to dupe people. I have already created a complaint at askgambler.com. It is so painful when you win and the idiots refuse to update your account. The earler they close that website the better for us all. Nobody can make me believe otherwise, cloudbet is a scam, i am ready to lose this money to them but i will ensure they lose most of their customers. They are criminals
