Awfull service from Nissan

I had a problem with my local Nissan dealership that I could not get resolved. I went onto the Nissan SA webpage to get contact details in order to contact them to assist. On the website there was a section where I could launch a complaint which I did. I never got a reply. After about 4 days I went back onto the website and found an email address with an invite to send an email to the CEO which I did. I got no reply. So now I would like for someone to explain to me why have a website at all if you never look at it or maybe just ignore queries from your customers who ultimately pay your salaries. The way companies do business in South Africa is like a fast spreading desease.
