The Georgia Supreme Court says Hanna is a "law firm," so you have to submit a bar complaint vs. them (and not a consumer complaint with the state OCA or federal FCC -- but fine if you do that too anyway).  You may submit a bar complaint vs. Fred Hanna (the owner of the "firm") and any atty. that may have contacted you that also violated bar rules for atty.s:

(Call and ask for a bar complaint, and if they have them online):

I took a chance and sent letter to a superior court judge in my district explaining my situation.His assistant returned a letter stating the judge requested her to reply to me.This is what she wrote: A credit card company is not required to produce a copy of the original card application signed by the customer in order to establish the existance of a valid credit card debt.However the credit card company will have to produce evidence of the debt in order to obtain a judgement against you.
Please respond to all pleadings from plaintiffs attorney by filing a timely response with clerk of superior court.Feel free to call our office at any time about all legal documents.I thought that was a good sign as judges are tired of all these lawsuits taking up court time and expenses.
