A new "research center" number, probably Bernett Research. A rogue data miner, implies that you gave permission because you didn't say not to...and they didn't ask permission first. Third parties skip tracers love 'em!
Just called. Never pick up numbers don't know. Called back and says number not in service at this time? Hmmm how does that get aloud. By Call Blocker and dump calls that didn't solicit. What are they soliciting that we don't want or ask for the phone call?
