This number doesn't call as often as I've seen other people say, but they do call me twice within an hour, every day. Never leaves a message. If they call again, I'll just block them using Legal Call Blocker for Android.

I've had multiple calls from this number with no messages left.  It's annoying!!!

Receive calls on daily basis sometimes hour on the hour.  No one there or receive message that "this call is not valid".  ??????

I received a call from this number and I said hello twice. There was a moment of silence and then they said goodbye.
