Who called from 2108586794

They are: Level 3 Communications, VOIP.  The White Pages website lists them as scam or fraud.  They call on SUNDAYS.

Too bad Whitepages didn't tell you that Level 3 is a phone carrier, like ATT & Verizon.  Too bad Whitepages didn't tell you that one of their customers is doing the calling or possibly Whitepages should have explained that numbers can be spoofed so the call could have come from anywhere in the world.
