Land Rover Ballito - disgusting after sales

We bought a Ford Kuga from land rover Ballito in October 2019, when we purchased the car we were told that the car is in perfect condition, and that the car was owned by the dealer principal sister in law, we were advised that all services were up to date. In February 2020( 4 months later) the gearbox was making a terrible sound, we then contacted the salesman and advised that the gearbox is making a terrible sound and that we want to return the car under the NCA, we were within our rights as we did not have the car for 6 months. We were then advised not to return that car as there was an extended warranty on the car and that we should take it to our nearest Ford dealer. We did exactly that, our car has now been at Ford for over a year, and only now did we receive feedback that the gearbox is damaged, but the warranty is not valid because the last service was not done at a Ford dealership. We kept in contact with land rover throughout the year, begging them to get involved to get the matter resolved as we were paying for a car that we had no access to, and land rover did nothing. I contacted the dealer principal who was so rude and intimidating, I asked if he would be willing to sit around a table and come to a decent compromise and he said straight out no,I was horrified when he told me that its been 18 months since we purchased the vehicle, and it's not his problem, it's our problem, he forgets that we stayed in contact and that we begged them to assist. We tried to return the car, but we could not because they mislead us to believe that the car still had a warranty, his sister in law owned the car, they should know that the warranty is not valid if its not serviced by a Ford agent. a gearbox is not something that gives up in 4 months, we are now having to pay for a car for 7 years that has R66 000.00 worth of damage. Stay way from Land Rover Ballito, firstly you don't know what you are buying, and their after sales is disgusting!!!!
