Poor customer service

Poor customer service. Reported multiple times about the issue with Suzuki vitara(14 months old) rear tyres and axle but it was ignored by the dealer and was adviced to change tyres. After 3 months Suzuki agreed that it has a manufacturing defect on its rear axle. Suzuki SA never tried to inform of any such defects until I got it checked privately. Now I was sent to 2 different tiger wheels and tyres but they both refused to do any changes on this car. Still didnt hear anything from Suzuki. SA. Have been forced to drive a car with almost worn out tyres.
