Novai Chain claims I need to pay a $1,700 "fund verification fee"

This is pi coin barter mall official websitethe third time they’ve introduced an unexpected fee after I completed all verification steps. My account was confirmed weeks ago, and I’ve provided all necessary documents. Yet now, they want me to pay this fee to verify my funds before I can access them. It feels like they’re just trying to keep my money. I’ve asked for more details, but they just tell me it’s part of their “standard procedure.” I’m beginning to doubt the legitimacy of this platform.
