LAND ROVER - UNSUPPORTIVE, UNETHEICAL AND BASICALLY UNDERHANDED

I brought a Discovery 4 to LandRover Hillcrest for a major service at 175 000km, which was carried out by this delearship. New Cambelts and various items changed to the tune of R25 000. 13 000km later, the motor seizes and Landrover opinion was "fair wear and tear". New sub assembly and machined top half, costs R142 000, which was paid, and I was given a one year warranty on motor. 11 months later, and 11 000km into the new motor, Massive engine failure, due to the plastic water housing unit, which sits between the sub assembly and the top half of the engine, splitting in two, and water drained from the motor so quickly, that it seized again. When I approached Land Rover Hillcrest for them to honour the warranty, they said, that they didn't replace the water housing unit, so therefore, its not under warranty and they basically walked away with no suggestion of assistance whatsoever. I would NEVER BUY A LANDROVER FROM THESE UNETHICAL PEOPLE OR ANYONE ELSE
