A collection agency put information on my credit report for a bill that I had for a XXXX cell phone XX/XX/XXXX. This was included in my bankruptcy back that I filed XX/XX/XXXX and it clearly lists XXXX and another collection agency that was trying to collect the debt at the time. This has brought my credit score down by XXXX points for old information. I have attached all of the information that is needed for review but if anything else is needed pleae let me know as I am in the process of trying to rebuild my credit. I am also considering taking the collection agency to small claims court as researching this was time consuming and cause credit to be declined.
