Can I use this info to my advantage to sue them?
Glad that you reported to all the appropriate official organizations. You coming forward as a victim is one step closer for the law enforcements to do their job.
Also, beware of using any law firms because cases like this is really tough and people who agree that they can do it, they just want to scam you. Do not pay any upfront fee or any fee until you are 100% sure that they are doing their job. Those people who claim they can help are legit firms to take your money away. They can always file as consultation firm and you would never get your money back.
Good luck!
