I dont know this number but they keep calling my cellphone every hour or so.  I have been away from my phone and haven't been able to answer. I also do not get good reception at my home so I can't answer it anyway. They wont leave a message. It is an Arizona area code and I do not have any past due bills nor does anyone have my cellphone number other than family and close friends.

This number will repetedly call you shortly after applying for or wanting information about a job posting.
My calls start after using a Heath Network Jobbing site.
These people bug you about on line schools even after you have checked boxes in the application not wanting futher education.
They will not leave messages and you can not returned a missed call.
The calls can be continuous for weeks !  Use the no call list opition,but don't expect it to work .

I currently receive calls from this number several times a day--it started after applying for jobs online.  They seem to be interested in selling me college.  I put them on the auto-reject list.
