Credit report -bull**** and **********!!!!

Actually I do not want to give them a star for a rating . I app**** for vehicle finance and to my disgrace it was declined!! Why??? Because of an account at Lewis Stores that was opened in Namibia!!!! After hundreds of calls I was told that it was an account at Lewis Keetmanshoop. I phoned them and they were friendly enough to help me. The account holder's ID and mine differs with the last 3 numbers. As the guy explained to me, the old Namibian id numbers consist of 11 numbers. So it seems that in SA that id was picked up under my South African id!!! BUT according to the accounts manager, the customer is an excellent customer of them and the account is paid up!!!! So HOW de hell does the account land up on MY credit report in SA as an overdue account???? And as far as I know, a SA citizen CAN NOT open an account in Namibia.!!!! Does Experian, or any other credit burea, not verify the information BEFORE loading it on a credit report???? I am now unable to get any financing due to this **** up!!!! So I want to know from Experian HOW do I get this off my credit report?????
