I wrote a letter to Experian asking them to investigate mistakes on my credit report. They wrote me a letter back stating that they refused to do an investigation. They said they were not going to do the investigation because they did not think the letter came from me. That 's ridiculous. They gave me a number to call to confirm the letter came from me but I could not speak with a live person unless I bought something. I think Experian is just trying to get me to pay for an investigation that should be fee.
