I had a dispute with Ventotrade (ventotrade.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: Good mobile app|No hidden fees|Easy withdrawals|Dedicated account manager
Cons: Minor UI glitches occasionally|Nothing significant
