seems to be a collection agency or some kind of service that tracks down people. Called three times today on my cell phone - no caller id shows up, no message left if you don't answer the call. When I did answer, they left a message with a number to call back and a case number and the name of a person I do not know who they were attempting to reach. I called the number back and asked them to take my number off that account, as i did not know who it was they were attempting to reach. We'll see if it worked!
