Are you a PR lawyer. I have already asked my lawyer to look into representing a class action on behalf of the customers. I could finance the litigation, and customers can pay me back out of what they win. Legally as a non lawyer, I can't share in his fees. But he can work on a reduced contingency, so customers can me back if they win. If they lose I'm just out the money. But it's hard to say when the best time to file is, as we don't know the extent of damages. Also, I may find some powerful information that would really help the customer's case, so we can wait to see what I find before we file. There is no statute of limitation has customer harm is ongoing and the extent of damages is still unknown. I do have all the customer's email address , so can also help get the customers on board.
