Your bets weren't placed within the ToS you have consent to follow to.
Your funds were returned to you, and the winnings were returned to the bookmaker. If you have a proof of these funds being taken without a reason - please share it. Until then we won't be replying to this question, the answer was provided dozens times already.
Sincerely,
1xBit team
Can you share how that player actually broke the TOS? Everyone can make such excuses without sharing any kind of information, if you present the mistakes of this user in front of everyone, it will be clear to everyone. We want you to work honestly and return the funds to all users.
But sadly you don't want to change yourself and try to deceive the users in different ways. It remains to be seen how long your activities will last.
