Your problem is that you don't understand what customer support is and what its responsibilities are, and what you should report to the security team with.
Then can you tell us the responsibilities of the customer support? I thought they're existing to solve the problem of their users.
Of course, customer support, as the name suggests, is there to help customers, simply not all problems can be solved within the scope of their competences.
Its understandable why you're defending 1xbit, the reason is pretty obvious. But its not a type of casino that you can recommend to gamblers, be honest.
I sympathize with 1xbit because it has been honestly paying me for almost a year and that is natural. I have never persuaded anyone to use 1xbit, everyone has different preferences and should choose casino (after own research) that suits him best.
In fact, I think it is one of the few sites that offers 24/7 support to the players. Live chat is very important nowadays. Many sites have a live chat but that is with limited times that they are available. I did read that 1xbit puts a limit on accounts with the maximum bet, but that is nothing new or more unusual. Often when you win a lot, you get a limit on your account. There are worse things.
