Rules are rules but the problem here is the rule itself. Just because FJ is a reputable casino in this forum doesn't mean you cannot question what's in their terms which I find unfair. They have the right to permanently close as every other platform but they have no right to confiscate what was deposited to them. They should allow him to complete KYC and withdraw before finally terminating the account. They could charge a service fee if they want to.
^ Definitely right and this mostly happens when people are lazy enough to read the TOS before using it. They think that they have been scammed but the sad truth and the fact they are not. We know all of here that how reputable their site is and as I remember there this was the first thread have seen that has a complaint against them. So, here is my advice, compile all your evidence towards them and submit it also in scam accusation board.
