Debt collector - leaves message, doesn't leave any identifying information.

If you get a call from them, it's Johnson Riddle and Mark law firm collections. It shows up as Unknown, but if you do a google search with the phone number and the word debt or collection, they pop up. Normally they call me for an outstanding debt but the caller ID shows up as Johnson Riddle & Mark. They're just trying to get more creative and sneaky while I am trying to file for bankruptcy.

My husband and I would like this caller and phone number on the DO NOT CALL LIST and it's Johnson Riddle and Mark law firm collections that doesn't identifying information at all. These so call messages are on a machine not a human and the machine calls three times a week. This has to STOP now.
