Bad after sale service

We bought Range Rover Evoque at the end of September 2014 at Merlyn dealership from Wener Oelofsen, two weeks later we discovered that the driver seat was damaged and immediately contacted him. He advised us to take the vehicle to the nearest dealer, Midrand was the nearest and we told to bring the car to them as they need to assess the damage. They finally indicated that the damage was factory vault. They order the seat. December 2014 we told that due to festive season factories are closed we hould expect the seat end of January 2015. February 2015 we contacted the dealership and we told that they are still waiting for the order, a month later we were told to bring the car for a second inspection and the following day we were told tha the seat was damaged by my wife jeans. This matter has been going back and forth till to date. Now the vehicle has breakdown last Friday, they indicate that they suspect that it was striked by lightning therefore it is not covered by Land Rover, we should contact our insurance. The serviceman made this assumption after he asked my wife whether it was raining on Friday. The car is still at the dealership were it was towed by Land Rover Road assistance
