Bad service

In November 2023 I traded in my Polo Vivo 2021 for Polo Vivo 2023 in Centurion Autohaus. This year in July I received an email from Fines SA informing me that I have traffic fines issued against my name, for the value of R3943, for the car I traded in. All offences were committed from January 2024, it means the car is still registered under my name. I called Centurion Autohaus, I wanted to speak to the salesman who assisted me, I was told he doesn't work there anymore, and I was referred to Stanley, who promised to forward the matter to his manager. I kept receiving the emails from Fines SA and I forwarded them to Stanley, but I didn't get any assistance from Stanley and his manager, the tickets haven't been cleared. I'm afraid this will give me a problem when I need to renew my Driver's License.
