I had a dispute with Impersonation of Crest Capital Australia Pty Ltd (crestcapitalaus.com) 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: Social trading features|Dedicated account manager|Competitive fees
Cons: Help articles are sometimes vague
