Range Rover Velar disappointing

After taking my Range Rover Velar for service i drove it to KZN to attend a funeral. At 77000 kilometres the engine seized in middle of the road. This was disappointing. What was upsetting is that there was no willingness from Land Rover South Africa to investigate the incident in order to understand what the problem was. Instead I was told the dealership did not touch the engine so it must be wear and tear. I had to sell the car at a loss just ensure that I don’t incur further expenses.
