Swiftrine Options just informed me that I need to pay a $1,600 “fund confirmation levy”

This wasn’t part of the sign-up process,Open an account on the official website of Pepperstone Foreign Exchange and I’ve never even heard of such a fee in any legitimate trading environment. I asked why this fee was necessary when everything had already been approved, and they simply told me it was a “mandatory cross-check.” No proof, no policy, just a made-up term. I’m starting to realize this might be their way of draining users slowly. Has anyone actually made it past this point and received their money?
