This number calls a lot but I never answer because I do not know who they are. I have blocked this number so the call does not ring and goes straight to voicemail. I also get other strange calls but I have blocked them too. Eventually new numbers pop up when they get tired of the numbers they have already called from.
Someone called me from this number held the phone and hung up. When I called the number back they did the same thing. And then picked it up and hung it up
