Reference XXXX Investigation Account # XXXX : This alleged debt to XXXX dating back to 2009 has been passed around among collection agencies. Their technique has been to send XXXX letter and when I do n't respond, they report it to the credit bureau. This latest is about the fourth or fifth attempt by different companies. Each time, their report has resulted in a reduction of my XXXX score, which is what alerted me to a problem. After resolution of this last complaint, my XXXX score went from XXXX to XXXX. This is a racket that needs to be stopped.
