You mean, they never gave YOU money. They've given it to others. I have a live account, as I posted earlier. So do others.
It's only a scam if they TAKE your money, which they haven't.
If you truly have not got your account yet, you should check and make sure that you did everything necessary. If you left something out, then you won't get your account.
Assuming you opened the demo and made your $500 already (you did open it in US $, right?), then...
1) Did you complete the application for a live account?
2) Did you contact them by e-mail at the proper address after you completed the application and attach your scanned ID to the e-mail?
Double check these steps.
If you left one out, or didn't do it properly, then there will obviously be a delay. With the number of requests they probably have to go through, I'm sure they just pass over any requests that weren't done properly and concentrate on those that followed the instructions.
