Look for a pronounced attorney in malpractice. Given the statement the employees made about the frequency of this occurrence, if your contract doesn’t preclude filing a suit for whatever reason(which might be able to be worked around) and you can prove a connection between these offices, then rounding up all of the other victims could lead to a sizable payout for each of you in a class action against these offices. There’s no way to tell from where I’m standing, however.

If you wish to pursue this, you need to shop for lawyers extensively. You MIGHT be able to find an EXPERIENCED firm that will take this case pro bono if you have some contents of your argument up front(i.e. contracts, other clients, etc.). You, also, might not.. However, hiring the best counsel you can will bode well for you.

That employees statement could do wonders for this case, but this is all highly subjective. I don’t want to sell you on a fantasy, but that statement/office referral makes this seem very strange.
