As One Financial Adviser is an online service, the EU Online Dispute Resolution Service is also available to contact the UK Financial Services Ombudsman. This is likely to change based on Brexit-related developments. You may also be entitled to refer your complaint to the Financial Ombudsman Service. More information can be found at www.financial-ombudsman.org.uk, or the EU Online Dispute Resolution Service, http://ec.europa.eu/consumers/odr/ (the ODR will forward your complaint to the UK Financial Ombudsman Service).
