Has called multiple times and does not leave a message.

Just today, May 11th (2016) at 9:39 AM; they attempted to reach me but I ignored its call because I didn't recognize the area code #. I did google and it stated that it's in PA. But, after ignoring their call, they didn't leave a message got me skeptical about its call as well. I definitely will ignore this phone number (724-381-1321) and I recommend you to do the same.

The man stated he was with student loan relief program and wanted to help me. He also had all my info. as for as address,phone number,social security no.,and full name. I answered his questions and then was put on hold,then the line was disconnected.I called back but didn't reach him or anyone the answering machine said I reached a google messaging service.

Keeps calling my phone 3 times a day. I dont answer and they leave no message

These people call my phone 24 / 7.  I keep looking up the numbers every time they call and I can see they are stupid ads and crap. I delete their numbers and black from my phone. But they keep changing their numbers. How can I get them to stop calling?  Isn't it illegal?
