I am putting another complaint on Experian because once again they continue to find ways to deny removal of the Federal Tax Lien they are reporting in which they got there information off of XXXX. I have confirmation from XXXX XXXX that the federal tax lien was removed from my risk file. I provided Experian the response from CFPB complaint XXXX from XXXX XXXX giving confirmation that the information was removed from my risk file with them. I have provided Experian with the police report filed, the form XXXX that I filed with the IRS, the response from IRS with receipt of my XXXX form, I provided them the response from XXXX showing the removal from where they originally obtained there information. With all of these supporting documents that uphold mt claim they continue to report and claim to verify this Tax Lien that is not suppose to be on my file. I am going to attach once again all the documents that I have supplied to Experian that only shows there unwillingness to help in the removal of fraudulent information that is on my file. They have provided only excuses and no clear answers. I am now requesting from them what vendor they are using to verify this tax lien. What is the steps and methods they are using in doing a legal full and accurate investigation. I am not asking for a generic template letter from them on how they do investigations. I want a specific list of steps that they took, including but not limited to the dates they contacted their vendor, the name of the vendor used and what was the steps. I would like to know if a website was used in trying to verify these tax lien and what is the address of the website. I have contacted the XXXX County Courthouse and I know it is not them providing the information so I do not want Experian to illegally tell me to contact the source when the court house was not the source used to verify the accuracy of the information. I also requested for Experian to remove the Fraud Alert from my file and provided identity verification documents for the removal of the fraud alert and yet it is still reporting on my file.
