Have no idea who this is, caller ID say "out of area" which they wouldn't be since it's my same area code.  They have called many times and always hang up on the answering machine, so I have them blocked.  They still call and call.  I figure if lefit businesses that have legit business with me can't leave messsages and identify themselves then I can't be bothered.  Guess they don't realize people work  (I usually work 12-15 hours a day) and I don't need to come home to my answering machine full of hang-ups every day.  Don't find this number online anywhere .
