more than likely they are calling from a number outta country & are able to mask their phone number to a New Your Phone. More than likely a payphone. Just gotta report it to the Attorney General & let them handle it.
I recently got a call from 718-874-0962 and they had got my name and number from a job application I had filled out on a site called applyhire.com. They were trying to get me to agree to receive either brochures and/or talk to someone at Strayer University. Why on earth would a reputable school need to scour job sites and steal information from people's resumes? I told them not to call back, then my junk email filter started to fill up on an almost daily basis with emails for free fortune-telling, free diapers, etc.
