I made a complaint on casino.guru. I also asked justbit to give me proof of any wrongdoing because they stated that they can ask for documents if they suspect anything. I didn't ask for any bonus, or had other accounts in the past on justbit. You guys have to understand that I do not play regularly and deposited just for that "No KYC" promise...
That promise is not guaranteed as for the security of the site they will not disclose their reason of doing that because your account is already suspicious. Most of the site can do this even if they claimed to be a KYC platform, this is why you have to read their terms and conditions all the time. If you can’t comply with their KYC then leaving that funds is your only choice and learn from this, if you can easily provide KYC much better.
Reason why we always check their TOS to determine if they will follow what words they say when they are claiming for something like that in future. KYC in crypto casino became normal thing so its really shady when a casino claim to be non KYC compliance since for sure a problem will exist the same like this in future. For now OP should submit all the documents ask since if that casino will not still process his request then this will be another scam casino exist which need to avoid.
