Caller ID says Bountiful, UT.  NEVER leaves a message.  Has been calling for a few weeks now.
I never answer calls I don't know or don't have a name in the Caller ID. I own a business on this line. If they're calling for my services they're told to leave a message and I'll get back to them.

"The number you have dialed is not in service, please check the number..." bla bla bla.   Spoofed fake.  I blocked my number and this is the result of my call back. I, too, never answer.  They are also calling my business line.
