very poor service

<p> i took my car for major service in menlyn on the 20/05/2016, and when my vehicle went there it was drivable and the person who test drive it also confirmed the vehicle being ok, after it was serviced a day later the vehicle started to overheat and it hit the water pump and valvers, and now the vehicle is standing after i paid this much forthe m to fix instead they damaged my vehicle</p>
