Complaint Review: BitHash24opx

I got an message on Facebook from a guy named Steven Winter, who claims to work for a Bitcoin Trading Company called BitHash24opx.  I invest in BTC, and he was polite, but aggressive.  He told me that if I open an account for $500, it would trade for a week and I would receive my returns.  I invested $1000, and at the end of the trading period, was told " I need  to upgrade my account in order to make any withdrawal". 

The cost to upgrade my account is $9600.  I was never told this beforehand, and am sick to my stomach for having been duped.  I already wrote it off as a loss, but I will not rest until everyone knows my experience with these con artists, and if I can save one person from them, then it's a win.
