Account listed XXXX under XXXX different account numbers. Mortgage servicing transferred between XXXX companies but only XXXX loan. Experian refused to correct and when I tried to upload documentation (included here) Experian placed a block on me so I could not. The XXXX date of delinquency was XX/XX/XXXX and the account fell off all XXXX reporting agencies by XX/XX/XXXX. Unfortunately the duplicate account is still present on the Experian report. By phone on XX/XX/2015 I spoked with (XXXXTeam Specialist) for Experian (would not give me any more identification) informed me that it is my job to verify the data with the creditor and to give Experian the name and number of who I talked to and they would follow up. I informed him that I wanted to know who Experian talked to for validation of my data and XXXX informed me that they did not have that information and was not required to have it. I asked him if the verification was done by automated response and he could not answered. I have enclosed the documents I was unable to upload through Experian below to validate my claim and hopefully get my Experian credit report to show accurate information. I have included a more detailed version of events below. Thank you.
