You can formally begin by making a thread of your accusation against cloudbet on this forum, simply locate the scam and accusation board (link to this board is already shared here by another user) and formally report your case in details.
Good thing is that cloudbet is one of the supposedly trusted casino thats listed on this forum, and i also believe they have a huge userbase on this forum as well, therefore a lot of users will be happy to study the case, take critical look at your evidences, contact cloudbet to hear/read their own part of the issue, and if in the end, it turns out your account was restricted unjustly, then be sure that they are either going to refund your money back to you or they will be blacklisted here.

But if in the other way round, it happened that you are the one accusing cloudbet wrongly, then also be ready for some tags.
wish you all the best bud.
