No Response To Dispute A Month Later...

I recently accessed my credit record to find a paid off account still reflecting. I called the number provided by Experian for disputes a number of times, only to listen to an automated response. I sent the relevant documents to the email address provided therein over a month ago, and to this day no response. These incorrect records are having an adverse impact on me and my family. How can a company with such a powerful role be so sluggish? This is unaccpetable service.
