The law firm made it very easy to join the suit once it was started they ran ads on forum and photography sites with a deadline ,it took a total of 9 months from the time I signed on till I had a replacement camera in hand.Have you sought legal counsel?
Why not, then solicit other parties if you have a case.
When the company's wrong they just wanna settle it as quickly and quietly as possible to the point of asking you to sign a non-disclosure agreement.
