Yes, I know about this company from the very beginning and when they started to follow the Traffic Monsoon path I knew it won't last long before they fail and scam people.
If you still can, then withdraw your earned money and run away, because you will never see your money again.
If this is not possible to withdraw anymore, I don't think there is something you can do from Vietnam by yourself.
You have to join together with other scammed people (like T.M community) and file a case against Futurnet.
There is always hope that the law forces will size some money from the company bank accounts if there are still any.
At least they go to jail but this is not the answer you are waiting for.
