POOR SERVICE AT BB SINOVILLE NISSAN

i bought a new Nissan Almera Active in January 2016,during that year i had a breakdown and it was at night so had to start by push and it started.I reported the matter to Alpheus Khobo my sales assistance on Monday and he had no clue of the problem and he advised me that if it does again must call road assistance.Last year 2017 had two breakdowns of the same problem,on the first incidence i called the road assistance for help and they came to pick up the car the breakdown driver tried the car and it started ,they left the car the matter was also reported but nothing was done. On the second incidence they fetched the car and the report that i got from them(Nissan) was that i was using the dirty fuel on the car and said i must change the filling station of which i did so.

This year 14 May 2018 had the fourth breakdown the car was taken to them and i was told yesterday that they cannot see the problem therefore the is nothing that they can do.
