Poor quality and service from Hyundai Northcliff

Reading the other reviews now and it makes sense. Bought a Golf 7 R cash purchase. Problems within the first week. Headlight loose, water/heating problem and a funny noise. Took it back to the dealership and the workshop checks and says they have to order a headlight. Before even reaching home, all warning lights come on and the electronics/power steering etc goes off. Booked in at Patrix.DP now informs that they wont be covering anything. It is clear that they sell mechanically questionable cars and with no remorse or accountability. Steer clear if buying pre-owned from here.
