No support from Land Rover management

I am beyond disappointed in Land Rover South Africa. My husband left a review on Hello Peter about two weeks ago they said that they will get in touch with him but to no avail. He emailed a thorough description of all the events that transpired to the CEO, CFO and other management officials of Land Rover a week ago, of which there was also no response. Our car has been broken from the 5th of November 2021 (almost 4 months now) and we received absolutely no help, no support, no direction or guidance from Land Rover. With our car still being under comprehensive warranty, logically there would be no reason for us to pay anything additional. Yet for some other reason, we now have to pay R30,000 with no clear indication of why the warranty is not covering this. I completely understand why Land Rover has this reputation - you don't care, management doesn't care and there is absolutely no service. I will never again in my life buy a Land Rover and recommend every single person considering it to stay away.
