No response

I've emailed Experian requesting them to update my credit report. I did not get any acknowledgement that my email was received or not . I tried calling them several times but there is no response. Firstly I struggled to get a report from them and when I finally did , it had old negative information. Now its a hassle to get them to update the information because I cannot reach them on the phone and also on the email. Must we always communicate via hellopeter? I'm sure they are very quick to sell service providers our information.
