Safe Concept Fx has just told me that I need to pay a $2,000 "transaction audit fee"

This came as a complete surprise to me. I’ve already completed all the verification steps,Domestic regular foreign exchange speculation platforms including submitting my identity documents, and was given confirmation that my account was fully approved weeks ago. Now, out of nowhere, they claim I need to pay this fee in order to process my withdrawal. They say it’s part of their “regulatory compliance” process, but I’ve never encountered this with other platforms. Normally, legitimate companies either deduct the fees directly from your withdrawal amount or disclose them upfront. I asked for a detailed breakdown, but they just repeated the same generic explanation. It feels like a tactic to prevent me from accessing my funds. They also said this fee is “refundable,” but I’ve heard that line before. I already paid an "administrative review charge" last month, and nothing came of it. This pattern of inventing new fees whenever I try to withdraw is incredibly frustrating. At this point, I’m beginning to think I’m being scammed.
