View FAQWhat to do if you run into an issue on ko33
Minor issues can occasionally occur on any online platform. If you run into a problem on ko33, try checking a few things on your own first — a weak internet connection or an outdated browser cache can often be the cause.
If you're unable to log in, try resetting your password first. If that doesn't work, your account may have been temporarily locked. In that case, contact support via Live Chat and they'll get it sorted out quickly.
If your balance doesn't appear after a deposit, don't worry. Note the transaction ID from your mobile banking app and send it to us via Live Chat. ko33's finance team will verify it promptly and credit your balance.
If you haven't received a bonus or aren't sure about the terms, visit the promotions page and read the details for the relevant offer. Each bonus has its own wagering requirement — typically 30x to 40x. If anything is unclear, ask our support team and they'll walk you through it in plain language.
Withdrawal rejections are usually due to incomplete KYC verification or mismatched account details. Upload your ID and make sure your name and date of birth on the account are correct.
