I was on the phone and got interrupted with this number. I called back and a voice message said the mailbox wasn't set up yet. I don't know who this is. Probably a telemarketer. Who wants to be interrupted by nonsense? There should be an enforced law against them.
Called my cell phone this morning. Fortunately, my phone was still in do-not-disturb mode from yesterday so I never heard it ring, and of course, no message was left. Based on the posts above, this number is now blocked forever and will never bother me again!
