I wrote a letter to Experian asking them to investigate mistakes on my credit report. They responded to me with a letter saying my letter was suspicious, and that they would not do my free investigation. I do n't know what was suspicious about it. It did come from me, and I even attached copies of my ID 's to confirm my identity. In Experian 's letter, they gave me a phone number to call and an e-mail address to visit to " validate '' my letter. Apparently, I can not speak to a live operator or do anything to via the web-site unless I buy one of their products from them. I believe Experian is purposely refusing to do my free investigation so I will buy something from them that I do n't actually need.
