Terrible service - don't ever use them

My vehicle went in for inspection on the 1st of December, fault was identified, i then emailed Deez from the service department on the 2nd asking him to put the claim in to the warranty company, he rep**** saying he is checking stock, i rep**** back asking him why is he working backwards(meaning sending claim to warranty for approval and while waiting for that check the stock) then i kept emailing with no response after that, on Friday morning the 5th he submitted the claim, he did nothing for 3 days, here i am driving a vehicle which i am risking my life with. today is the 8th i called the dealership(nissan umhlanga) to find out if the spares are in stock they said no they will only order the stock once they get approval. I was made like a fool for 1 week when my car should have been fixed by now. They coming with excuses that they had an audit, so which means audits take preference over customers life???? today i had to drop the car off at the dealership for the assessor to come verify the claim, i asked for a courtesy car they told me that they don't offer that and even if they gave me a car i must sign for the insurance of R100k excess which i am liable for if anything has to happen to the car. This is the worst service from a Nissan franchise, i will make sure to post my journey with Nissan Umhlanga all over social media.
