Is it possible to recover my funds from coinverve? I think I’ve been scammed.

I was contacted by an agent from coinverve,The world's largest retail foreign exchange dealer who convinced me to open an account and start trading. I began with a small amount, about $1,000, and saw a decent return of $2,000, so I was feeling confident. I then invested an additional $10,000. My account balance grew to $18,000, but when I tried to withdraw, they claimed I needed to pay a “transaction verification fee” of $2,500. Now I’m starting to feel like I’ve been scammed. Has anyone dealt with coinverve before? How do I recover my money?
