I did not answer & they left no message

Received call from "Omni Foinancial"  Told him I was too busy to talk right then.  He said he just wanted to verify my street address which I verified.  Don't know who Omni Financial is but I got a few possibilities through Google.   Most likely choice is a company offering help for those with tax liens and garnishments.  The state just filed a lien against me so I suspect Omni Financial is calling to fish for new clients.......  Just a guess however.....

"Please hold for the next available agent........."
No idea who it is or what they want so I just set the receiver down to tie up the line as long as possible.

Called the number back.  The automatic voice said "Omni Financial."  Not familiar with who they are and why they'd be calling me.
