This company is making a lot more sense now. In the other thread, it sounded like they were a genealogy company that was finding info on speculation. Now it appears to be something I am familiar with.
A few years back, I got a letter in a hand addressed envelope stating that the state of Florida might have money for me, and for a percentage, they would collect it for me. I thought nothing of it until I got a second letter from someone else. So I did a bit of research and found the state website where that information is posted and sure enough, I had several thousand dollars waiting for me. A past mortgage company had over charged me. That is also where unclaimed bank accounts of deceased people goes.
People make a living by looking through these records and then try to locate the people who are owed for a percentage. In my case it was easy because all I had to do was look up my own name and fill out a form to collect it without giving anyone anything.
