this number called, left no message. i don't answer numbers that i don't recognize

Has called several times in 2 days.  Never leaves a message.  Has called several times in the past.  Does not respond to text messages.

Just got a call from this number and when I call back it says restricted.  

I know all about that. It drives everyone else around me nuts but who cares! It's my phone & I can do as I want with it. I don't know the number, I don't answer. If it's anyone who knows me then they know enough to leave a message if they really want to talk to me. Lol

Ok. i just called that number and was entered in a sweepstakes by an automated service. All I had to do was answer yes or no to a few short survey questions. Sweet! Yeah... Like I'll actually win something!
