Withdrawal is still pending

I would like to report that my withdrawal from Fx Direct Trade Global Trades (www.fxdirecttrade.com) on Oct 6 is still pending as of today. My initial fund was 300$ and it sooner increased to 5000$. At first I need to pay 20% of the profit to the company as commission. So, I added the needed amount. But the withdrawal status is still pending and transaction in process. Then, I was subsequently advised that I have to pay the blockchain fee of 3000$ which I did not pay at all. Please help me.
