Srewed by land Rover South Africa

Brand trust is a foreign concept to Land Rover South Africa.I bought a brand new vehicle from Land Rover South Africa. Only to find out the vehicle is issued with standard 21 Inch tyres,however I was supp**** 20 inch tyres.However as a I signed the handover certificate ,i accepted the car as is.The problem is my spare is 21 inches and the rest of the tyres 20inches.Tough luck Mr customer .Buying a new car and from the Brand owner you dont expect to be *****ed over.News for me
