Pinnacle Credit Services review: Sending bills i dont owe

Received a bill from Northland group a collection agency saying in the mail saying I owe another collection agency $1120.33 for a bill I owed for Nyseg..I never had Nyseg In my life and Why would a collection agency have another collection agency contact me about a bill that is not for real?..I do not owe this money and Am tired of both Pinnacle and Northland group collection agencies calling me and sending me false bills in the mail when I am on the do not call registry..Please make sure they stop this kind of behavior and lies.I do not owe this money.
