Parts not replaced but charged for

Terrible service by Hyundai Centurion on 01/04/2016. Took my mum's car in for a service and firstly could not find the service plan on the system and could not offer any explanation or offer to investigate. I agree to pay for the service cash.<br> <br> Next rant, the car is only on 20 000 km and and was told that the brake pads are completely worn. For a small car that's hardly used to require brake pads replacement at 20 000 km is crazy at a cost of R2000 for front pads and wiper blades which were still fine.<br> <br> After getting home I looked at the \old\" parts and saw a new air filter in the box. When I checked the filter in the car it was dirty indicated that it was not replaced. <br> <br> This is terrible service by Hyundai Centurion, I will never use them again or recommend them to anyone. I highly doubt that the car was inspected properly and that everything that that I was charged for was replaced.<br> <br> Reported this to the service advisor and have not received any explanation for the horrible service or an apology.<br> <br> "
