Bad customer service

My husband purchase a vehicle cash in the beginning of July. The same week the car was taken back to the dealer due to the malfunction light being on and the feedback we received was nothing was wrong we must have kept the lights on.Two weeks later the same thing happened and for second time this was the feedback.Then in the middle October the vehicle made a funny tapping sound and when my husband contacted the dealer they told us that the warranty is only a month and need to sort this out ourselves.The salesman Bruno then told us the manager Less Herring said that he is not entertaining this and sort out the problem.We then took the car to Dodge to have a look and done a oil change that cost us R1500 and we need to have the car taken back to the dealer.I have informed them via email that need them to acknowledge my complaint for the Consumer protection act and it was asked only then to have the vehicle brought in.I have asked them to give me the contract that reflects the T &C because nothing was given only the registration papers.My vehicle is still with dealer currently and not receiving any feedback ,only that the vehicle cannot be driven.I feel that they should refund the full
