How to get in touch

For assistance, send an email to support@mrocasino.best. Our team can review your request and provide information relevant to your account or the service. Responses are usually sent within 24 hours, although the time may vary depending on the nature and complexity of your enquiry.

To help us respond faster, include the following in your message:

  • The email address or username connected with your account
  • A short, clear description of the issue or question
  • Relevant dates, transaction information or error messages, where applicable
  • Screenshots if they help show the problem; remove any passwords or other sensitive information first

You can contact support about account access and verification questions, deposits and withdrawals, bonus terms, technical problems, or responsible gambling requests. If your message concerns a payment or account security matter, do not include your password or full payment card details.

Please send one clear message about each issue where possible. This helps the support team understand what you need and reduces the chance of important details being missed.
