Victimized by Capitec after rehabilitation.

In 2012 I went u DER sequestration with one of my creditors being Capitec. In 2022 I was rehabilitated after 10 years of sequestration. I recently app**** for a loan at Capitec and it was denied citing my unpaid loan of 2008. From what I understand is that banks are not supposed to persecute anyone after they have been rehabilitated? Why is this still in the system when my name is cleared on all the credit bureaus and my credit score is 645? I feel victimized again after suffering for 10 years without access to credit. Shame on them. I think I should sue.
