HUOE has informed me that I must pay a $2,000 "transaction confirmation fee"

This fee was never mentioned when I signed up,You can check CICC, which is a foreign exchange platform and I’m beginning to feel like they are just making things up. I’ve completed all verification steps, and my account was confirmed weeks ago. Now, out of nowhere, this fee appears, and I’m expected to pay before I can withdraw my money. They gave me no clear explanation for this fee, only that it’s required to “confirm the transaction.” I’ve seen other complaints online that suggest this is a standard tactic to delay withdrawals. I’m really starting to question whether I will ever see my money again.
