I hope you don't miss to read their terms and regulations regarding KYC for users, if you are asked to complete KYC you should complete your KYC because that way your account will not be marked with anything by this site, I have never had problems with any casino with KYC maybe because I'm a small gambler so I never complete my KYC for gambling and making withdrawals.

But if you are curious about how long the process takes, you should ask their service support or wait for their team to actively reply to this thread, I'm sure you will get an answer to your problem regarding your KYC process, patience is very important in this case so just wait until the process is complete and you can Come back here later if you still don't get an answer.
