Poor service from Nissan

On the 15th November 2018 i bought a brand new Nissan Qashqai 1.5 DCI Tekna (BB SILVERTON) within a week of buying the car i had a problem with the locking system. I went to the salesperson and he thought its the keys and took in the keys.

The problem continued and in december i went to report again they checked and couldn't find anything. In January i took the car in and when it came back they told me that the problem is fixed but the problem continued and i had to again in January take the car in.

In February the problem got worse and i took the car in to Nissan again but still no solution. I reported the matter to Nissan SA but no solution to date.

I am now stuck with a 2 months old car that is having locking system problems.

My number is ********** 462
