Poor service From NTT Ladysmith Nissan

Poor service From NTT Ladysmith Nissan My Nissan NP200 has a factory fault on the paint.The vehicle is 1 year and 7000 on the clock.Since October 2020 we have been going back and forth with them,they refuse to replace it and now have sent it for a respray. They took the vehicle on 18 of January 2021 and was promised it by the end of the week. On the 22 they brought the vehicle and the colour does not match,the door does not match the side panel they painted,overspray on the black trimming and full white in the bin.They took it back and brought it back on the 29 January with nothing done to the vehicle. Today the 3 of January 2021 they asked me to come to their office to view the vehicle.They resprayed the rhino-lite with black paint in the back bin and did nothing else. Can you believe it they would spray over rhino-lite?I have sent it back for the 4th time now.They refuse to give me a courtesy vehicle for my business. The branch manager Charles & workshop manager Kobus also acknowledge they can see the difference and still call me to view the vehicle repeatedly. Thank You Kavir Sarju
