A rarity among the scum-suckers known as debt collection agencies, the guy who called me today from this number not only left a message, but he left his name ("josh"), his employer ("Sentry Credit"), AND his purpose in calling ("I'm a debt collector calling to collect a debt"). Gotta give the guy credit for honesty, at least. Now, it could be a gazillion people in this "firm" all using the name "Josh", but, hey, that's more info than we usually get from one of these folk.
FWIW, do a quick Google search for "Josh Sentry Credit". It'll lead to a LinkedIn.com profile of him (at least, it looks like him--lists his full name and the fact that he works for Sentry Credit).
This person called for the first time and left no message when I called back they answered as Josh with some Credit company couldnt get the name he said it to fast. Since I have no issues with a credit company I think they called the wrong number. I have no interest in talking or explaining who I am my sister did that once and it took another month for them to stop calling her looking for info on another person she knew nothing of.
