Vehicle Pre delivery inspection failed dismally

I purchased a Mazda 3 from your Nissan Gateway branch. Its really not been a very nice experience having to deal with the issues that was addressed after i collect the vehicle in Germiston. If a proper pre-delivery inspection was done on the vehicle before transporting it down to JHB all these issues would have been identified and sorted out. When i collected the vehicle a few things needed to be addressed, Right hand side folding mirror did not work, rust on the roof of the vehicle and rear tyres had flat spots. These were then brought to the attention of the sales manager and sales agent at Nissan gateway who arranged with Nissan McCarthy Ens Street JHB to assist. The vehicle has been with McCarthy since the 26 August 2019. Simon from the end street branch has been awesome at assisting me in getting all these addressed issues sorted out. He managed to get the rust looked at and sorted, replaced and replaced the rear tyres. Only problem is the folks at the gateway branch. They decided that the mirror which has now been a delay for almost two weeks will be bought and couriered down to JHB, they first bought the wrong one which only had 3 wires and then bought a second one the stated is the correct one and sent it down just to find out its still the incorrect mirror as it had 7 wires instead of the six it should. Simon now had to suggest to the gateway people that the mirror be bought and fitted in JHB as they did with the tyres. Its been two weeks of over promise and under deliver from the McCarthy Nissan Gateway staff and i do not get informed of anything, i need to constantly call in myself and get updates. I've had the pleasure of driving this car for one week only since taking ownership. I spoke to the dealer principle whom i also had no joy when the call was done informing me that they out of courtesy are helping me get this sorted and that its only been 1 week and 3 days without the vehicle. That is very inconsiderate telling me indirectly that its not even that long. I will never recommend your dealership to anyone, you can also tell your agents who has been trying to conduct a courtesy call with me to remove my number from your records, next one to call me will be treated like you treat your customers. Even if this is not a new vehicle and a used one treat people with respect like you would like to be treated when you buy something that you will be responsible for paying for the next 5 years. I really do not care what you do going forward to inconvenience me because I decided to voice my frustrations, that karma will return to all of you who treat people like this. Going forth speak to Simon at your McCarthy branch in end street and refrain from contacting me. Tired of being fooled by all of you
