I disputed inaccurate information with Experian regarding the accounts that are listed on this dispute. First of all, I 've contacted the companies via USPS certified mail and sent them a letter of debt validation. None of these companies responded with any verification or validation of the accounts or the information regarding the accounts. By law, these companies are supposed to verify to me that these accounts and the information is accurate. I would like to know what verification/ validation did Experian receive regarding these accounts that was competent since they say the investigated my dispute.
