Same here for a few days actually. No message left.

I had back to back missed calls from this number and when I called it back I blocked my number; a woman answered the call asking if I were available. I hung up.

I been getting the same calls too. They been calling and hanging up on my voice mail several times lately so I called and the same thing happened to me today when I blocked my number and called it back. It is starting to get on my nerves now!

This number keeps reportedly calling and leaves no message!

hey guys, they called me too. its an education service that you either clicked on their website and they got your number or they called you back for you showing interest somewhere in one of their services.  heres what I did and they stopped calling me.
I dialed  *67 412-405-6124  the *67 blocked who I was ... then an automated service answered and asked me to enter my phone number for their 'do not call list' they havent called me since. hope this helps!!!!
