Look for the information about the license from the gambling commission the best Netent casinos uses. This information can be found in the footer of the casino’s website or in their terms and conditions. Write the description of your situation in English. Apply screenshots of all the mails from the casino and your account balance. Use the contact details of the commission that can be found online, for example, support.mga@mga.org.mt or info@gamblingcommission.gov.uk.
