I just had the same thing last night (7-25-2007) and then when I mentioned the case number, the rude guy on the phone asked me to call back in 10 minutes or else they'd issue a summons and hung up! Furthermore, I heard another man in the background call someone "baby". Very rude, and as a law abiding citizen, I am not sure what that was all. I can tell you that the phone records from other sites point this to Adairsville, GA and this is a cell phone number, from what I read. It also connected me to some asset site which I have no idea is.
I forgot to mention that I got something like "Americana business" or something like that out of him, but they weren't very clear, and would not give out the who's or what's that they allegedly are.
I received a strange call from this place trying to collect on a credit card bill that is 20 years old. They would not give me their address so I could send them a cease letter.
