OneCasino customer support

The main email address comes from OneCasino's About us page, while the availability statement appears in its terms and conditions. Treat the round-the-clock statement as overall support availability, not a guarantee of an immediate email reply or a separately confirmed chat schedule.

Languages and regional support

The terms' support-hours statement does not name supported languages. Ask whether an agent can assist in your preferred language before explaining a complex issue. The Dutch contact address is a regional contact detail, not proof that every support channel provides service in Dutch or English.

OneCasino links to regional sites at nl.onecasino.com, dk.onecasino.com and onecasino.es. Include the domain associated with your account when contacting support. This matters for escalation: the Spanish site identifies its operator as FPOOCL S.A., rather than One Casino Limited, so the MGA-related complaint route described below should not automatically be applied to a Spanish account.

The MGA register identifies onecasino.com as the licensee's website. The website displays a chat button and Help centre link. For email, the published address is listed above. The following checklist is practical guidance about describing an issue, rather than a list of operator-mandated requirements.

1. Identify the account and issueState the account's regional domain and describe whether the problem concerns access, a payment, verification or a game. Use a clear subject line.
2. Provide relevant evidenceInclude dates, transaction references or the exact error message where relevant. Screenshots can help explain what happened, but remove unrelated personal and financial information.
3. Ask for a specific next stepExplain the outcome you want and ask what action remains outstanding. Keep the correspondence together and request a case reference if one is available.

OneCasino's terms say a withdrawal should be approved or denied within five working days. That wording concerns the withdrawal decision, not a promise that money will reach your payment account within that period. The terms also state that additional identity verification applies to any withdrawal request, and that any applicable fees are shown on the withdrawal page.

• Ask whether the request is awaiting verification, awaiting a decision, approved or denied.
• If documents are outstanding, ask which specific requirement remains incomplete.
• If the request was denied, ask for the reason in writing and the relevant terms.
• Check the payment destination: the terms say withdrawals normally return to the deposit method and only to an account in the player's own name.

For more detail, see the OneCasino withdrawal guide.

The MGA register lists One Casino Limited as licensed under MGA/B2C/327/2016 and names eCOGRA as its approved alternative dispute resolution body. OneCasino's company details identify One Casino Limited with Maltese registration C 73399. Check that these details match the operator responsible for your account before choosing an external dispute route.

1. Request formal complaint handlingTell support that the issue remains unresolved and ask for the applicable complaints procedure. Set out the events, supporting evidence and remedy you are seeking.
2. Keep a written recordRetain messages, payment references and relevant screenshots. Ask for a written explanation of the operator's position and whether any internal review remains available.
3. Check eCOGRA's requirementsFor a dispute involving the MGA-licensed operator, check eCOGRA's current eligibility and submission rules, including any requirement to complete the operator's complaint process. Its register listing does not guarantee acceptance or a particular outcome.

OneCasino's footer warns that gambling can be addictive and links to Responsible gaming. If your request concerns difficulty controlling gambling, say so clearly rather than treating it only as a payment complaint. Avoid further gambling while trying to recover losses. See the responsible gambling guide for guidance on recognising harm and seeking help.
