Poor Service

<p>Okey where do I start: I bought a Mazda 2 from Mazda Centurion it had only 23km on the clock, after a while the car started to shake when idling , then we thought maybe it was just dirty filters or something so my car went for a service , we told them what the car a doing and that there is a knock on the front wheel, then we got the car back but it was still doing the same so we told them about it AGAIN, then they said the car doesnt do that when they have the car so we waited a while and took the car to them when the car was doing it so in the meantime I called MAzda SA in midrand and they said okey book the car in , we did like they told us. they tried to find the problem for 3 weeks, replacing stuff as they go because they could not find the problem. SO MY CAR GOT A WHOLE NEW ENGIN AS THE CEO OF MAZDA SA SAID REPLACE IT , THEN THEY REPLACED THE GEARBOX AND THE SHAKING STOPPED FOR A WHILE. Then my husband took them to drive the car on dirt road as the ABS was making a noise and the knock was still there. them they told us the ABS pump needed to be upgraded and after a month it was replaced but still waiting for a part to fix the knock on the wheel after they replaced the steering shaft a while ago. then when we got the car back from mazda for the ABS pump we had another problem now my car is telling me I can drive almost 780km on a 40 L tank. then they told us okey we need to replace the cluster on the car. SO I AM ASKING HOW LONG MUST IT GO ON LIKE THIS THEY DONT WANT TO REPLACE MY CAR?????? my car is not even a Year old and it has so many problems?</p>
