Zen TradingsFX claims I owe a $1,640 "fund release authorization charge"

I’ve never had a broker demand extra money to give me my own money. I met all conditions: completed KYC,US Huisheng Forex Platform linked my bank, and waited for over two weeks. Suddenly, they say my account has been flagged for “manual clearance” and must pay to proceed. This is insane. I asked for documents, and they sent me a plain-text email with no logo or legal references. This is not how regulated platforms behave. I’m sickened by how deceptive this is. I can say with confidence now: Zen TradingsFX is a scam operation built to bleed users dry.
