Do not argue first. Build evidence, stop sending more money, create a timeline, then complain through payment and regulator routes.
If support asks for tax payment, VIP upgrade, more trading volume or extra margin before withdrawal, stop adding funds.
Save dashboard screenshots, withdrawal request, deposit proof, chat logs, emails, KYC records, trade history and timestamps.
List deposit, withdrawal request, support replies, extra demands and settlement status by date.
Use platform ticket first, then regulator, payment provider, bank dispute process and public complaint records.
