scam and unable to withdraw

Managers of Belem Exchange,declare that the currency bem, ‏Either it remains blocked for ‎90 ‏days or its value reaches ‎30 ‏usdt, ‏withdrawal will be allowed. ‏Now that it has reached above ‎30 ‏usdt, ‏they announce that we should recharge our account with ‎1% ‏of the total capital so that the bem currency is freed. ‏This is fraud. ‏If they are telling the truth, ‏they should deduct from our total capital and give the rest of our money, ‏please take care of it.
