Misdiagnosis, Unjustified Additional Charges and Unprofessional Service Experience

Paid R30k for repair after diagnosis, but engine fault returned within 24 hours. Dealer misdiagnosed the issue, demanded further payment for a new quote for something that was not in the initial quote , kept my car for two weeks unresolved and the Service Manager was rude and unprofessional. I had to follow-up every time for my car . They misdiagnose the car and except you as the customer to pay for their Incompetence .
