Nissan qashqai reg: KM94PJGP

I've taken my car to North West Nissan in Roodepoort on the 02 December 2023. Car has been losing power (Nissan Qashqai 1.6 aventa tech AWD). So around mid December I contacted Nissan South Africa and open a case to speed up the process. Since the 2nd of December till around the 5th of January 2024 I've been phoning North West Nissan and Nissan South Africa as none of there staff at the branch or Nissan South Africa phoned me once to give me feedback. So on the 13th of January 2024 again I've contacted Nissan South Africa and I've requested for feedback and the lady I've spoken to say she is not allocated to my case but she will flag my issue with a manager and the person that opened my case to give me an update on my vehicle on 15 January 2024. Today is the 16th of January 2024 and still no one at Nissan contacted me. Seems like Nissan has no knowledge of there own brand as my car apparently can't get fixed! Not too sure what can take so long as they can't seem to locate a problem and also there is no urgency or importance regards to my vehicle. So now I am battling with one car. What happens if my current car brakes who will be paying a rental car cause Nissan is taking there sweet time in repairing my car?

I would like Nissan to either purchase that vehicle from me and repair it on there own time. OR Provide me with a car that I can use while they try and fix my car OR Give me a letter stating they can't repair my vehicle and that they recommend to right of the vehicle In order for everyone to carry on with their lives. It is not my problem that Nissan can't fix my vehicle and they don't seem to care about the issue at hand. I've warned Nissan South Africa that if no one is going to phone me on the 15th of January 2024 I am logging an complaint but still that didn't help as Nissan in general doesn't care about their own customers. Reason why I am going through this is that I've tried selling the vehicle to we buy cars and they just refused to buy the car. That is how bad the car is. This is also my first Nissan we've bought and been the most regretted discussion me and my wife ever made! Nissan phone your customers!!!!!!!!!!! Christo - ***
