It's been 2 weeks since this post was posted. What move did you get from FortuneJack? Were their customer service representatives able to provide you the help that you need to your concern? I have read a scam accusation to them yesterday too but it was a different story with the same ground of lost money. You can post this topic on Scam and Accusations board so that they could look into it and investigate it. If you know it to yourself that you are telling the truth, there's no need to worried about. Just provide all the evidences and proofs you've gathered and include it the next time you will post. Screen recordings, screenshots of history, screenshots of conversation with the cs that you talked to would definitely help.
The amount you've lost is definitely not just small so it's really something to be bothered of. Just continue to communicate with them and if they will neglect your concern, you can escalate it further so that they could learn their lesson.
