I have recently pulled out my credit profile from Experian company. I have found out XXXX or more accounts that are incorrect, I have contacted the credit report company, Experian, to ask them to investigate the incorrect accounts that affect my credit files. But Experian sent out the letter that said " we received a suspicious request in the mail regarding your personal credit report and determined that it was not sent by you ''. ( see attachment ), although I have enclosed my government ID and a recent electric bill. The reason I have sent many letters to ask Experian to investigate, because Experian has listed many incorrect items and infomation on my credit report. I can not send XXXX letter to ask Experian to investigate for XXXX or more items that are incorrect. It just does n't make any sense to me to receive this letter from Experian. They Just wanted me to dispute online via their website, and I did. But when I tried to dispute the incorrect account and they did n't let me do it. They said it was investigated for previous disputation. Now I try to access their online result to attach with this letter, but it said the system error ( see attachment ). I 'm not satified that. Please help me to resolve this matter. It affects my life, and make me distressful. 
Thank you so muchtruly Yours, XXXX XXXX
