I read your case from the beginning, seem like you are taking the bonus deposit from them and playing some match UFC. You also got the problem with "malicious activity" and try to withdrawal the money but they asking you to do KYC.
Just want to ask with you, about the bonus you are take did you already fill the requirement maybe reaching some wager amount or anything. Because the bonus offer sometimes always have some rules/requirement, you cannot withdraw the money until meeting the requirement.
But, still suggest to you to create some scam thread since they are ignoring your problem with a long time.
