Goldeneaglescoin.com complaint: Scammed in the name of investment

My complaint:

I have invested over 1000usd with the company cold goldeneaglescoin.com where I managed to accumulate over 500 000 usd within a period of one month.

So when o want to withdraw the money they demanded that I must pay 450usd of which I did . And they never released the funds but they demanded more money.

Suggested solution:

I please need assistance to recover my money with the promised interest . They must pay out all the money that shows on the system.
