Experian sent me a letter refusing to conduct an investigation of errors on my credit report because they said the letter was suspicious. I am attaching a copy of the letter I sent them to this e-mail, and there is n't anything suspicious about it. I even included copies of my 2014 XXXX and drivers license to verify my identity. They gave me an e-mail address to go to so that I could verify my investigation request XXXX. After entering in my information, they told me I had to mail in my request. Well, obviously, I 've already done that. They also gave me a phone number to call : XXXX. I called it, but I ca n't get out of the automated system and speak with a real person unless I buy something from them. The investigations are supposed to be for free.
