ExtrodigitalPro emailed me today saying I need to pay a $1,800 "capital harmonization fee"

I had never heard of such a fee,24-hour precious metal trading platform and nothing about it appeared in the terms when I opened the account.They claim it’s required to align my account with their international liquidity protocols. That explanation sounds completely fabricated to me. I’ve already paid a “processing fee” and an “AML check” weeks ago. Now this?I asked if this was legally required, and they just responded with a generic “this is part of our compliance model.” No details, no regulatory documentation. I’m beginning to feel like they’ll keep inventing these charges until I walk away empty-handed.If anyone has encountered this “capital harmonization fee” or anything similar, please share. I don’t want to waste more money. I just want to know if I’ve been scammed or if there’s still a chance to recover my funds.
