Well evidence is the most important thing, especially since the OP said that BC.game gave a fake hash and also proof of chat with his support, if this is strong then it needs to be reported in the above format.
As stated by @aioc, this gambling site turned out to have had complaints before but BC.GAME gave a good statement, so for the OP if it is true that you gambled purely and did not commit any abuse then you will be stronger to provide evidence.
