No Response from Experian SA

For weeks now i have been trying to call Experian to speak to a consultant due to a possible negative credit profile but nobody answers the call on the number listed on the website. i have sent emails but still no response. It is quite obvious that a number of large service providers in SA are using Experian to rate consumers but if we cannot get hold of these people to correct the wrongs how do we move forward with our lives. My Transunion report is perfect yet i still get negative ratings from Experian. Experian should take a leaf out of the Transunion book and learn how to accomodate the peoples lives that they impact.
