Sueluan

I am a US citizen.
Someone introduced me to an online gold trading platform OTOFPR and earned quite much gain.
But when I apply funds withdrawal, I was required to pay personal tax to the British Financial regulatory bureau.
So I was treated the same way as that of Mr. David Lockwood to pay my personal tax of 286459.95 USDT to British Tax bureau through OTOFPR platform in July, 2024.
Later, the platform asked me to pay total of 1,050,560 USDT verification fees for my identity verifications.
I feel I was scammed by the platform. Is there anybody else having the same experience as I had ?
Please help to identify that we may regroup to complain to the US government.
