I am responding to a letter I received from Experian regarding a suspicious request made on my credit file. Based on my understanding of the letter, it looks like Experian is refusing to complete my request because they believe the letter I wrote them was not sent by me. 
I would like Experian to know that I did in-fact send them a letter disputing information on my credit report. I also give Experian my expressed and written consent to continue with the investigation of my accounts per the dispute letter I wrote to them. 
I would also like to know specifically what made my letter " suspicious '' and why Experian thinks I did not write my letter to them. Did I say something in my letter that they think I am not smart enough to write myself? 
I have reviewed Experian 's website to determine what steps I am required to take to dispute my accounts and thought I had followed all instructions : I sent in a copy of my ID, proof of my social security number and proof of my address. I would be very grateful for a step by step explanation from Experian detailing the specific information I may have missed from their website. 
I do not have the financial ability to be represented by an attorney. I work all day and can not afford to take time off work to dispute my accounts. So I would like Experian to tell me why is they are choosing to not accept my letter and my humble request for an investigation of my accounts?
