This number calls my cell phone almost daily and on some days more than once. I'm using a great app that allows me to block a call, meaning my phone won't ring and the call goes to voice mail. Of course they don't leave a message, they do keep the line open. If I listen to the VM, I can hear people in the background.
Regarding the note I posted.
As I was posting the message, they called. My phone forwards it to voice mail. I can go to the apps voice mail options and there's a search the Web option. Today it notified me that the call was coming from New Zealand. Granted, they may have programmed their phone to say that. It's some information
