I have disputed several incorrect and inaccurate items on my Experian credit report. Unlike XXXX and XXXX, who both performed proper investigations and ultimately removed the accounts from my reports, Experian never performed a legitimate investigation. I received a letter from them dated XXXX XXXX, 2015 that they previously processed my disputes and that the credit grantor has verified its accuracy. This is impossible because the other XXXX credit reporting agencies were unable to verify it, thus deleting the bad information. Furthermore, Experian refuses to reinvestigate the same dispute. This is absolutely ridiculous. So instead of submitting electronic disputes, I sent dispute letters in the mail. I received another letter dated XXXX XXXX, 2015 saying that Experian believes they received suspicious requests in the mail regarding my personal credit report and determined it was not sent by me. How can they possibly determine this when the return name and address on the letters belong to me, and I personally signed each letter and included my social security number. They simply refused to comply to my dispute requests and delete inaccurate information they are displaying from the following creditors : XXXX XXXX, XXXX XXXX XXXX and XXXX Bank. Moreover, they have restarted the 7 year time clock for which these tradelines naturally drop off of my credit report which is yet another violations of the FCRA. I am utterly disgusted with Experian and request a full investigation of their practices along with my ignored disputes.
