Who called from 2107143099

why do they call every other hour just to hang up on me???

They are robo calls - auto dialers that dial numbers looking for a phone pick-up. junk call, just hang up as soon as you hear silence.

This is another Google business listing scam.  I have added this number to the ever growing list of blocked numbers.

They left no message.  When I called back, it said the number was not in service.

Never answer
Don't even pick up
Just block
