Warranty not hounoured and *********** dealer network

The only way to get Nissan to contact you is to leave a bad review on this site. Lodged several complaints on their website and just get ignored. My case is also just ignored and told sorry the dealer wont honour the warranty, wehn in fact the issue is not only with the dealer but with Nissan SA> Theit claimed warranty is not honoured. I sit with a car with no working aircon that was faulty within the warranty, but because the dealer could not fix the problem correctly after 4 attempts and now the vehicle is out of warranty, I am excpected to pay R 12 000 to sort out. I even got charged for regassing the aircon by the dealer when that was not the main problem. I will not keep quiet until Algoa Nissan and Nissan South Afica are taken to book.
