I have been disputing a debt which is not mine for months that is showing in my credit report as XXXX account number XXXX. I have written to XXXX several times at the address provided in the report, which is XXXX XXXX XXXX XXXX, CA XXXX. It turns out that this is an incorrect address for XXXX and has not been valid for years. This has cost months of delay in this process and Experian will no longer take a dispute for one reason or another. And I can not clear this up with the creditor since Experian does not list a vaild address, which I believe is the responsiblity of both Experian and the alleged creditor to have valid contact information listed under the FCRA.
