Experian - At least answer your phones

I am trying to update my credit record for an account that was paid up 10 years ago that still reflects on Experian as in arrears. I have tried to call the Experian call centre and their phones just rings with no answer I have emailed Experian numerous times with no reply. This is very unfair to a consumer as we have a life to live and cant because we are being held back with inaccurate information on experian and get absolutely no help
