You can file a civil lawsuit. You may or may not be able to persuade the prosecutor to file a criminal case.

The video near the middle of the page shows fairly clearly what they did, with accurate and understandable descriptions of shady behaviour. I think a capable prosecutor might regard it as difficult to prove that behaviour illegal. Shady, sure, but in dubio pro so why even prosecute.

So that leaves a civil lawsuit. There's no need to persuade a prosecutor for a civil lawsuit, and the balance of evidence counts, there's no in dubio pro.
