Debits outside the loan agreement

I had a loan with Capitec. As per the loan agreement the term was July 2019 to May 2025. I kept checking the banking app for updates and indeed, my loan was ending in May, 14. To my surprise when I checked today, there is an additional fee that will still be debited in June. Who added the additional fees on the loan? Why was I not informed.

The worst is that I spent my day being sent from pillar to post in the Collections department. No one knows exactly how this happened. All the WhatsApp numbers to contact also refer me to other numbers. I've sent an email to Client Care and got a call that referred me back to Collections dept.

This is how Capitec treats paying customers.
