They always call and then hang up.   They call all the time and do the same thing.   It is very nasty.  I work second and third shift.  I wihish they wouldn't.   Please find out.   Thanks   Joy

They are career specialists

It's not a real career specialist. They call from all sorts of numbers. Most likely what happened was, you filled out something online that wasn't real or something shared and it was passed around. You can save these numbers on your android phone under whatever you want and then block them. This is #3 for me that I've blocked since they started calling me.
