No feedback /communication from Capitec after they failed to updated my credit listing at Credit bureau

I settled a loan with Capitec in May 2020 after I was offered a discounted final amount to pay. Soon after making the payment, I received a settlement letter. However, Capitec failed to update my details at Credit bureau. I wouldn't have known about this if I didn't check my credit score. This is 6 months later. Now, I am set back with my goals and no feedback or apology from Capitec after sending countless emails. How unprofessional Capitec
