Bad service Planet 42 and third party

Where do I Start. Bad service. Bad, please think twice before you decide to do business with them. There deposit is low but the service is not up to standard. First when I required about cars with them, I received wrong info of the cars. Then when I arrived the first time after arrangement was made. I must bring my wife with me to sign for the car. Then when we arrive the next day. The car I wanted was not fixed as arranged. Then I look for a different car. Then we had to wait almost 4 hours to get the contract sorted. Now 5 days later I picked up that the brake pads on the car I finished , we inform call centre and they told us that they can't do anything about it as we need to take the car back to Menlyn. I am staying in Edenvale which is plus min 45km away from me. Driving with no brake???? Really. Then I spoke to a guy called Trevor. First he gives me an attitude that I contacted him on his cellphone. And he also informed me to drive the car to Menlyn. When I asked him who will pay for my fuel as it is not my fault that the car brakes is finished as they were supposed to do a mechanical check before they release the car. He told me that ,that is not Planet 42 issue as the sales person is a third party who assists them to sell cars for them.

My question is ,is the onis still on Planet 42 to get the car fixed or mine? They released a unroadworthy car to me. Am I correct?

I believe the service I received is below the standard of any vehicle dealership in Gauteng and Pretoria. I really did expect better from a huge company like Planet 42. But it is shocking. Please help me if I am incorrect??
