Anyone heard of Franke Schultz & Mullen?

Here we go again ... I had a payday loan from Total Lending in early 2008 (among many others). When I finally closed my bank account and tried to get out of this mess, I had overpaid Total Lending. I sent them a C&D letter along with notification that I had overpaid them. Instead of responding to me, they sent my account to collections. Each time, I tried to deal with the new collection agency by sending DV letters. Each time (I think 3-4), instead of handling it, they just sent it on to another collection agency. In March of 2009 I eventually filed a complaint with the Ohio Attorney General's Office, and then I received a letter from Total Lending apologizing and letting me know that I should not hear from any other collection agencies regarding this account. Then, just a couple of weeks ago I received a call from a Mr. O'Reilly from DA Network saying I owed over $900 for a $300 loan that I'd already overpaid. I then told him I'd alrready dealt with this account through the AG office. I faxed him a copy of the letter I'd received from Total Lending. Then today I received an email from the rep I was dealing with at the AG office with a letter from Franke Schultz & Mullen indicating they were "writing off" any account with me for their client, Total Lending. The letter also said that they had already notified me of this. I have never heard from them. The letter is addressed to the Ohio Atty General's office. Has anyone ever heard of them? The other interesting thing is that the letter is dated 9/11/09, which is the date I faxed my letter to DA Network, and the letter references a previous conversation on 8/29/09. I had not even contacted them by this date, so how are they talking to the AG office before me? Any ideas?:confused:
