I have asked Experian to investigate and if not verifiable delete negative information on my report. I have explain and shown Experian the mistakes such as re-aged, recent monthly payments on accounts that are closed and they have fail to provide me with validation of accounts from collection agencies. Experian has responded twice that the information is accurate according to the furnishers of the information, also sending a final notice that unless I send additional relevant information that supports my claim they would not re-investigate the dispute accounts again.
