Disappointing NP200 customer

Not all the buttons for the aircon on my NP200 were working. Nissan SA did not want to pay before inspecting the part as I had claimed it from my warranty. I had to pay for the part, but the wrong part was ordered / delivered. I then took my bakkie in again and when they finally installed the part it was still defective and my aircon was now only pushing out hot air :( (very uncomfortable). I am very disappointed and even regret taking my bakkie there.
