The faster they hear from you, the better the chance of stopping or recovering the money. Below are the official fraud and card lines for 1 provider in Monaco.
Do this first
- Call your bank’s fraud or card line now. Use a number from this page, the back of your card, or your bank’s official app. Never use a number from a text, an email, a caller or a search ad.
- Block your card or freeze your account in the app if you can, and change your online banking password.
- Ask the bank for a reference number, and write down the time you reported it.
- Report it to the police as well: see who handles cybercrime in Monaco.
- Keep everything: messages, call logs, screenshots and transaction IDs. Your bank will never ask for your PIN, password or a one-time code.
