Land Rover N1 City - Worst service experienced from a dealership. Issues still unresolved.

Booking my mom's new Discovery 5 in for a service with a list of issues that we had listed for them, I was told by the only service advisor why did I not make an arrangement for this before I brought the vehicle in. I then explained to Rashaad that I had let Edwina Pearce know about the issues before booking. She had also called me back to make sure of one the issues so she could advise the Technician. The vehicle was booked in on Thursday the 18th of November. The first call I got back from Rashaad was the Friday, no call to give me any feedback or even ask if it is ok for the vehicle to stay overnight. The Friday call was to tell me that the vehicle is still not complete as they are waiting on parts. From taking delivery of this vehicle in January 2021 it has been in and out of the dealership to try and sort out the wifi that has never been working. This is just 1 of many other issues experienced for the short ownership of the vehicle. The front passenger seat got messed on with some type of thing that just will not come out. I approached them to ask if they could have a look and see what can be done - I was told unfortunately we cannot do anything about it. I do believe the seat was damaged in there care. I have sent emails and tried calling Land Rover SA with no response 1 week later. I also escalated the matter to the service manager Bennie De Swardt and it is just like they do not care always passing me back to the service advisor. We have been Land Rover owners for many years and this has with no doubt been a very bad experience with the brand. Today is the 2nd of December and we still do not have our vehicle back.
