It ain't over till it's over! Please feel free to peruse this thread as it does kind of make the procedure evident. The people here, particularly Alias and Roxy, were incredibly helpful. It's vital to get complaints filed with your state banking authority/AG/BBB. The most vital step is closing your bank account. And every PDlender gets a certified C&D letter.
I was also lucky because I'm in NJ, and PDLs are illegal here. They go to bat for you just by being listed on the complaint.
Just start your own thread and people here will help you through it. In your opening post, list all your PDLs, amount borrowed, and amount paid. Tell us your state. There are links embedded throughout my thread that can help you too. There are templates you can use to base your letters on. Good luck!
