MP Registration, License Disk and Roadworthy fee with Service feess

We bought vehicle in July 2025. Mobilis Auto Cherry Kempton Park charged me already on my vehicle contract for mp registration and license disk. Plus we had to do roadworthy test again for R570. Now the Dealer Principal Amanda Louw don't want to give me back the R570. She said we got thr vehicle when it was still two months valid.NOBODY and not even the sales person Given told us aboutvthe two months roadworthy timeframe. Appart from this, I emailed Mobilis Auto my banking details? With the Invoice of R1310 and the R570 for Roadworthy. I am still waiting. What must I do nowwwww???!!! Francesca
