They keep calling my work number.

Missed the call; no message was left.

called 6/10/2016 ID YOSEMITE NP CA left no message.  BLOCKED #

Unknown name with this number.
A man said "hi, is so and so there?" I say "who is calling?" he hangs up.
He knew the name to ask for.
The connection was odd, sounded like under water...strange.
More calls followed and w/o answering but constant calls through out the day.
:/ Auto calls or some type of connection to keep calling.....

left a loooong voicemail that's unintelligible, like s dialogue from tv or something in the background. creepy/weird!
