Complaint Review: Convergent Outsourcing inc

I got a call a couple of months ago from this place saying i owed over a thousand dollars on something i knew was a lie so i kept telling the guy i know for a fact i dont owe them anything and he was a scam and he just hung up on me.  Now a few days ago i received a fake bill in the mail from convergent outsourcing, inc 10750 Hammerly Blvd #200 Houston, TX 77043, saying they are collecting a debt for jefferson capital systems for a capital one visa in the amount of $1129.91 but they are willing to settle the debt if i send $564.96 before a certain date to convergent outsourcing, inc PO Box 9004 Renton, WA 98057, which is the second address on the paper, and there is a third which is ATERSO01 PO Box 1022 Wixom, MI 48393.  I know this is fake bill i have never had that credit card and i check my credit report regularly, And i owe nothing.  Watch out for these people  they will try anything to get your information.
