Experian Uncontactable therefore not responding on fixing an incorrect default

I have been trying to speak to an agent telephonically every working day for a month regarding my dispute, yet I have not gotten any feedback or anyone able to answer a telephone. I emailed eza.consumer etc with no response! In my opinion Experian is very quick to list whatever blows their hair back, but so super slow to assist with a problem they created. I have a listing on my profile that not even the name of the credit provider shown on the listing is aware of. It does not help to write mails as Experian is simply ignoring one. What will it take for Experian to give us the service when a dispute is raised of incorrect info on one's profile. For them it is so easy to brush us of by non communication, but for us it is a nightmare as that default is hanging over your head like a guillotine, and you cannot proceed with your house/car purchase. Sies Experian Sies!
