Bad Service

I took my suzuki to suzuki west rand 3 months ago for a service i ask them to look at my central locking because it doesnt lock my doors always with the button on my door and my boots buttton to open the boot never works and they told me they will look and the afternoon i ask them about it when i pick the car up they said they didnt look because they havent gave me a price but the car come with the central locking its a suzuki dzire GL and about a month ago i ask them to look at my aux and Bluetooth port because it doesnt work they just tested the fuses and just say they dont know what it is and say i can go they dont wanna do extra effort at all even my door rubbers began to tore a while back SUZUKI IS DEFINITELY NOT THE BEST....
