Who called from 3103585875

Calls every single day. either says nothing or pretends to want to provide a service

Called again at 6:03pm.  Their call was blocked before they dialed my number.
BLOCKED FOREVER

5/02 10:44 Just tried again.  Will they never give up.  Only rings once on my end, so NOMOROBO seems to be working because call blocker doesn't show the number being blocked.

Same as above, caller blocked, still called again. Even only one ring but annoyed so much!!

Ditto, called, I answered, nobody there, blocked in silence mode.

When I review my "missed calls" at the end of the day, I delete from my "land line" and make a note of the phone number for future reference.

You would think the NSA could figure this C**P out in the interest of national security.
