It is a debt collector... If your not dodging paying the bills you owe then answer it. By some chance they have the wrong number, ask them to remove you and they will.

phone number calls but leaves no answer very annoying when i can answer it at work and thinking its an emergency with my children or something

no message, no name on caller id

Got a hang up call from this number and called back.
