Called my land line in Detroit MI at 10:01 am but left no message.
I did a tremendous amount of research on this number, and discovered that the calls are coming from a direct line from Bolgia Five in the Eighth Circle of Hell: Maleboge. This one is reserved for grafters (peculators, extortionists, blackmailers and unscrupulous businessmen: sinners who used their positions in life to gain personal wealth or other advantages for themselves). They're punished by being thrown into a river of boiling pitch and tar. In addition, should any of the grafters try to escape the pitch, a horde of demons ("Malebranche", meaning "evil claws") armed with grappling hooks and barbs stands guard over them, ready to tear them to pieces.
Rang twice and hung up.
