Claims to be a Natalie Davis and leaves a message that makes it sound like she is about to have a warrant issued for your arrest, but is troubled by some of the details.

Called the number back. They refused to provide an address to send a debt validation letter to. She stated they don't give out addresses since they only take payments over the phone.

recieved several phone calls from collection agency with local number 617-849-8437.  when i explained that it wasn't us they are looking for...they would hang up on me.  I hit re-dial and was connected to Natalie Davis at this number.  She assured that the calls would stop.  

These people seem like complete bottom feeders.  I was told they are DRS out of Greenville SC.  Nothing found on line.  Must be CRS.
