unable to withdraw with hidden fees

After several months of trading, I made a few small withdrawals of $3,500 from my account that I received on a wallet. When this account reached $4M, I made a $150K withdrawal. But this withdrawal was conditioned by the payment of an operational fee of 2% of the account amount or $79,715 to be paid within 14 days before a penalty per day of delay of $3,985,75. These fees do not appear anywhere on the site and no negotiation is possible to reach the settlement of this sum. However, settlements were made, the largest of which was $63000 with a third party account but this settlement was rejected and returned. The $20,775 settlement with a registered account was not returned to me. These actions are not normal.
