Static Mainner is now demanding a $1,750 “settlement execution charge”

I have Large foreign exchange trading platformcomplied with everything they’ve asked for, including submitting ID, bank proof, and even doing a compliance call. Everything was marked approved. Then out of nowhere, I get this message about a brand-new fee. I asked where this charge came from, and their answer was that it’s “part of the backend withdrawal sequence.” What does that even mean? I’m starting to believe this platform is just finding creative ways to delay payouts. If anyone has gone through this, did you actually receive your money?
