How to secure a compromised bank account

Immediate actions

• Call the fraud number in your official app or on your card
• Freeze cards and stop pending payments
• Change your online banking password from a device you trust
• Ask the bank to review and remove unfamiliar payees and device registrations

Close the wider gap

• Recover and secure the email address linked to the account
• Ask your mobile provider about SIM-swap protection and port-out locks
• Review statements for small test transactions preceding larger ones
• Ask whether the account should be closed and reopened with new numbers

Documentation

Keep every reference number, the date of each contact, and the name and role of each person you speak to. If a dispute outcome seems unfair, that log is the basis of an escalation to an ombudsman or regulator.
