Experian not correcting their errors

I've been trying to correct information on my Credit report for months. I've emailed Experian on numerous occasions, and each time I receive a reply saying that the corrections have been made only to find out later that it hasnt.

This incompetence and lack of integrity is alarming considering this company handles all of our personal and sensitive information, which can have a massive impact on the quality of our lives.

Please get this sorted out once and for all Experian.
