I dealt with Hanna & Associates, they have been in many lawsuits, the biggest I believe was the one for not having an actual judge/attorney (can't remember which one) sign off on their paperwork which is required. They were just going around stamping stuff that wasn't legitimately authorized by the proper person.
However for me, I knew it was my debt and was just ready to be done with it. Do your homework though, but most importantly you have 30 days to respond to the court, don't mess with those days because they are the type to go after the default judgement for you not responding.
Good luck!
