They wouldn't tell me who they were with, just "an important business matter" and couldn't tell me more till I told them my address. Yeah, no thanks. So, I never found out who it was.
I get calls from this number and other similar numbers (same6 then 3856, 3699, etc) EVERYDAY! If I answer, no one is there. And I've called back once where an automated message wants my info. I have no idea who it is and I can't figure out how to get off their calling list. It's super annoying. And creepy!
Actually, I just called back and when they asked for my number I just pressed 0 and I actually got to talk to a person! Stellar recovery services is who they claim to be, a debt collecting service. They were calling to reach a person who no longer owns this phone so they said they'd take my number off their list.
