Unable to Withdraw Funds From Metamask Due to Continuous Payment Requests

I installed the Metamask cold wallet app and purchased USDT through the Binance system, which I then loaded into my Metamask wallet. However, every time I try to withdraw funds, the system demands additional payments. Initially, I was asked for a payment for account verification, which I made. Then, I was asked for a fee due to Ethereum C20 fluctuations, followed by another payment for the mining pool exit. Now, they are asking for a 15% tax payment for the funds to be transferred to my account. I suggested they transfer the funds to my bank and deduct the fee from there, but they refused, and my funds remain blocked by the system.

I am in contact with customer relations and managers from the Metamask mining pool and ETHGO on Telegram, but I am still unable to access my funds. I am not well-versed in this matter and would greatly appreciate any support or guidance you can provide to resolve this issue.
