Actually, yes.
I let them break the law and recorded every time they did it; either by copying every document sent between us, or recording every phone conversation that we had. Once they had racked up several violations, I filed a complaint with the Attorney General of Ohio. My complaint demanded that the debt be wiped out (in writing) and confirmation that the debt not be sold or given to any other debt collection agency for collection. I also demanded statutory damages for violation of FDCPA. They gave me everything but the money, and stated in their letter that they denied any allegations of illegal tactics. I filed my lawsuit the same day I received that letter, seeking statutory damages under FDCPA.
Once I had filed my lawsuit I negotiated with their lawyer (If you file a suit in small claims court, a corporation MUST hire counsel; they are not allowed to represent themselves) for settlement. They attempted to settle for half of what my judgment would have been, but I negotiated 80%.
They hired their counsel the day before our trial. Had they not shown up I would have asked for a restraining order against the company (since they attempted to collect after cease and desist, and also after their letter stating they would not attempt to collect), and I also would have sued the company that issues their bond allowing them to be licensed to collect. I would also enforce my judgment with a garnishment of their wages.
I did not hire an attorney. I handled this entire case Pro Se.
