Wow, received a call from a number not yet listed in this database?

No message was left when I refused to answer or wasn't home. Any idea? (313) is a Southeast Michigan area code... Detroit, I think. My parents used to have this code before they started changing area codes every 10 minutes back in the late 80's.

Good old interwebz: According to it, this number belongs to something called "Complete Metamorphosis", but there is zero information on it, except it is a private company with an approx. payroll of 2 and make approx. $91,000 per year in revenue.
