Best way to report an USA based ICO for suspected fraud and gross negligence?

[e-networkassociates]

Has anyone here done so, and if so how did you go about it?

Does anyone have a link to resources where one can report a USA based corporations ICO?
If there is a "cheat sheet" or online link where a best case approach to reporting can be reviewed?

It is looking like the cost to litigate versus how many thousands I invested is on par or more depending on how long they try to stall proceedings in court.

So the next best thing is to have a regulatory agency have them cease and desist and investigate their conduct.

My sincere thanks in replying with your help and insights!
