First, I think you should not use harsh words like scam and
associate it with an entity without solid evidence. I assume if you
had solid evidence, you would have sued their asses off and get
what you wanted, but the fact that you posted here without
seeking legal counsel suggests you do not have solid evidence.
Secondly, if you want a way out of this situation, the best
people to talk to are those who have the authority to help you out.
I feel that by airing your grievances online, it may do more harm
than good for you personally.
If you really think there's something really fishy going on and
you have proof and for some reason don't want to seek legal advice,
then go to the media for help, and justify your case to them.
