Pathetic poor service received from Nissan SA, no care for their clients

I cannot believe the pathethic poor service received from Nissan SA. They could not assist with a loan vehicle from the Balito branch as they said all their loan vehicles were out and my vehicle, a 2012 Nissan Murano was out of warranty with Nissan but I have an extended warranty with a 3rd party, but that is not an old vehicle and definitely not a cheap vehicle. Nissan SA treated it as if its such an old vehicle so I did not qualify for loan vehicle. I find it unbelievable that Nissan SA does not have a contingency plan for clients if all loan vehicles are out. I had to spend most of my holiday money to hire a vehicle on my own account (about R8000) and everytime I mentioned the importance of a loan vehicle to the consultant, they would say they would get back to me and then silence. My vehicle has been in repairs at the insurance panel beaters from mid Oct, awaiting backorder parts from Nissan which had an initial ETA of 31 Dec. This is so unacceptable as the parts not being available is out of my control and i had left my vehicle there in good faith, not knowing I will be so inconvenienced due to the parts from Nissan not being available and not even being escalated/expedited to arrive earlier. I then found out that the part was ordered as a normal order instead of a VOR order. It was extremely imperative to have a vehicle as my job depended on it but still no sympathy or empathy from Nissan SA and no assistance. I was eventually told that my part would be in country on 3rd Jan 2020, but still nobody tried anything to get me a loan vehicle. The insurance company went over and above and gave me car hire for about 50 days, but Nissan SA didnt even come to the party to assist me as the client in any way. I believe they did not understand my dilemma and my urgency or just didn't care to go over and above to assist a client. They did the minimum in getting back to me on the ETA and that was it, even though I stressed the importance of having a vehicle. How do I replace all the money that I spent to hire a vehicle due to Nissan not willing to assist... I guess I cant hey, my cost to bear due to choosing a Nissan SUV vehicle instead of going with my usual vehicle brand which I had no issues with. But this was truly an eye opener. Really upset and not a happy Nissan client at all.
