I'm not killing your hopes but I guess there's no hopes for your issue to be resolved. This casino has a red reputation, but I guess they are trying to get their green repuration back.
I wonder what "fraudulent act" they are referring to suspend your account. Do you know and did you did anything wrong and againts their policy?
1xBit representative is trying to sound that they are trying to resolve the issues to make it appear to new users that they are victim while running their campaign on other sites, it's time that this gambling site reported to the domain registrar and their host because they are using these platforms to scam people which is a big violation of their TOS, they are no different to scam ICO.
