Damaged car

i bought my car on 16/09/2014 from henque motors, and from the very first day i drove it from them it gave me serious problem like leaking oil and water, making a funny noise in the engine but their technician could not find anything wrong with it, but the oil kept on leaking very bad and the noise was increasing louder and louder but Pieter insisted that the noise will go away and turned me away from the dealership refusing to help me, now my car has been stuck since february, and the mecahnical warranty wants full service history of that car and the dealership has still not provieded me with the service history, and ive been asking for the service book of my car since the day i bought it but they keep on saying they will send it to me, ive also asked for a spare key but nothing, please help.
