Refuse to Clear my name after Rehabilitation

I was sequestrated in 2008 and my ABSA accounts (Credit Card, Vehicle Finance) was part of the insolvency. However in 2012 I was rehabilitated. ABSA however refuse to clear my name on their system. Every time I apply for credit at ABSA it gets declined due to bad conduct of previous accounts within the group. This is not in accordance with the insolvency act that states that once a person is rehabilitated, that person is discharged of all debts which were due, or the cause of which had arisen, before the sequestration. Section 129 of the Insolvency Act.
