Keeps calling..no message..dial tone after I pick up

I receive calls w/no messages left...ID states call is from Tennessee

THIS NUMBER CALLED ME TWICE AT 3:00 AND EARLY IN THE MORNING AT 7AM. NO MESSAGE. AND LOODED IT UP FOUND OUT IT WAS A TENNESSEE NUMBER!IF ITS REALLY A NAVY RECRUITER.. I ONLY TOOK THE ASVAB ONCE AND DID NOT SIGN OR GIVE MY NUMBER TO ANYONE!

I never managed to pick up my phone on time, i tried calling back but there was no answer.

I did a search and came up with Navy Recruitment papers. If you have filled out your name on any military website that would be how they get ya. www.cnrc.navy.mil/publications/NOTICES/1001Notice_Jun08.pdf
