Poor service and lies / I will never buy a Nissan car again

See ME Buying NISSAN car again KILL me... Last year March my car was booked in at a Nissan kimberley only to get it end of August after 5 months. I took it back when the parking light was flicking but nothing was detected ... Other problem occurred when I was on holidays in haartebees North West on the 11 July 2022 mind you my from Kimberley Northern cape, it was booked in at Brits Nissan on the 12 July 2022 I was told for me to get a courtesy car warranty must approve first which was approved on the 15th July by the I have already made arrangements out of my pocket to go home after 4 days extended vacation. 18 July 2021 I was told I cannot get a courtesy car because all the parts needed to fix my car was there, okay I kept my cool and wait for them to perform magic.... I got a call from Nissan south africa that the warranty also approved for my car to be delivered back to kimberley, okay right things looked good for a minute. I recieved another call from Nissan brits apparently there's a part missing but the car is drivable and one the 1st August my car was taken from Nissan brits and delivered to Morgan Nissan kimberley on the 11th August after many calls of enquire. A lady called Terissa or trishia at Nissan warranty was handling my case and called say the car is in Morgan Nissan I can go fetch as it is drivable waiting for part ***Q1A however technicians in Morgan kimberley suggested that I can't drive it nissan south africa must provide me with courtesy car as the missing will only be available after 21days. When calling Nissan south africa I was told Terrisa/trishia warranty is not allowed to talk to clients but dealership mind you I spoked with her previous days... Now is one month in without a car I have to pay money everyday to transport my kids to school and myself to work my movements are little/disadvantaged . I had to cancel my daughter's sport class and the****** because of Nissan. I real tried to stay positive but is too much having to keep going as if everything is normal when is not.
