Who called from 4808987000

This number keeps calling my cell phone.  I don't know who they are and they never leave a message..

Yea! Same! They started calling me two days ago...and never left a message also...

This number is for Lamson College located at 875 W. Elliot Road Suite 206. Tempe, AZ 85284.
They are a Private for-profit, 2-year institution which has a Program Participation Agreement with the US Department of Education for eligible students to receive Pell Grants and other federal aid.

I received a call from them after I answered one of their ads.

So no need to answer the call!!!
