Four days without a car nor courtesy Car after my car was towed to Nissan kimberley

Hellopeter Wednesday the 31st March 2021 around 8:50am when starting my Nissan qashqai 2018 1.2 which is still under warranty it started shaking and powerless around 9:29am I called Nissan kimberley and spoke with Magda she asked me to give her car information which I did and she pick it on her system as it was only serviced there for the passed 3 years which the last time was 15th January 2021. She asked if I can be able to drive the car to them Nissan kimberley I said no she said I must call Nissan South Africa so the can tow the car to Nissan South Africa. I did and my car was authorized to a towing company my Ref No:21-***-R-01. At 11:53am the tow truck tow the car away and the consultant from Nissan South Africa called back asking if the took it away already or not she was so helpful to be honest I then asked her about Courtesy car as I still have to fetch my kids from school and work plus my planned holiday, she said Nissan kimberley are responsible to make that arrangements for me. However Nissan kimberley Never called to let me know the received my car or what is wrong with the car. I called them 14:40 and spoke with Magda again and she said there are still going to check what is wrong I asked her about courtesy Car she said she will speak with her manager Madelein Lubbe but she never get back to me. April the 1st I called them medelein promised she attending to my case. I don't how many times as I lost count try to find out what is the way out my calls where in vein as I was sent from pillar to post and no information at all on what is wrong with the car. 16:40 I called again and spoke with Magda she said the technician went out testing the car she will let me know now now, which I had to call her myself to find out only to be told the car is no drivable as the need to order injectors and I asked so what now she said the don't have courtesy car to give as I must call Nissan South Africa just 17:00pm I asked why didn't you tell me that on time because now everywhere there are closing because of long weekend she said the don't close. I called Nissan south Africa Road assistance the consultant told me because the car was towed at home not 100 km way the can't give me a Car and the other call center closed at 12:00 ..Nissan kimberley must be the one giving the car. I call medelein and Magda who where very disrespectful and not taking me seriously the gave a phone to the technician trying to explain but I told him Im not saying I need my car back but courtesy which the keep on saying the don't have and is not their responsibility to give me one. Medelein ended up saying I must just come and take my car as it is because I'm giving her grief... She gave me numbers of her Principal Manager Johan Boysen who was not helping also as he even suggested I must cancel plans because he can't give me any car... Even today I don't have any car and no one ever called to tell me what is happening. Please help because I believe on the 31st march or 1st April early Nissan Kimberley would have told me their intentions so that I can call Nissan South Africa on time but that never happened I had to loan someones car for my holiday which bookings where made outside Northern cape +-500 away from home. I'm not happy all with the service from Nissan Kimberley and the way the speak with costumers.
