I had a dispute with Quantum AI (pyzlatiksof.cfd) and went to their complaints process. They have an internal team that just defends the company. Then they said I could go to an ombudsman - but the ombudsman they use is industry-funded and rarely rules for the client. The system is rigged.
Pros: Professional team|Full transparency|Portfolio tracking tools
Cons: Email notifications too frequent|Account statements could be more detailed
