After Sales and broken promises is disgusting to say the least...

I bought a Datsun Go from the East Rand dealership in august 2018 and to tell you the truth it has been the worst experience of my life. For a 2018 vehicle it has already had to be repaired and a whole history of negative experiences follow. When we did the deal with them the sales rep was asked if the jackets came with his words were if the deal is approved then yes he will get jackets (not bothering to tell us they are on back order) Obviously the deal went through as i have the car but since then to now i get thrown aside as after sales is something that does not exist in Nissan. I have been speaking to JP at your call centre for two days and from they will phone me( which they have not) to he is a owner so who cares what he does with the business although in my eyes he is putting your brand out there and as much as my complaint seems to be a silly one in everyones eyes this was a promise to us and i honestly feel that this should be kept. You cannot tell me in all the Nissan branches around the world not one of them has these jackets that can be arranged for the clients sadly i find that impossible at the moment for such a huge company. I have been made to feel that i am complaining about a stupid thing to been felt unimportant to just blatting been in the way and it is really sad as i thought at the time this was a good deal and i was really happy in the beginning with the service from this branch until it was signed on the dotted line then everything went for a ball of **** and no one cares.. Yes i am frustrated as i would think any complaint no matter the size would be important
