Nissan South Africa can not provide parts for the cars

I am totally disappointed with Nissan South Africa..... They released a new car in July 2021 NISSAN MIGNITE, I bought a car. I have an insurance for my car. My car was bumped by an old man on 13 December 2021 who was affected by stroke while on de parking lot. The car has been taken to de Penal beater n I rented out a curtussy car for 30 days from my insurance. Nissan is unable to provide with the parts n also can not provide the date of which when can the parts be available..... 😭😭😭😭

My 30 days for de rented car has passed n I have been told Dat I must make a plan for my self where to get de car, in order for me to use on a daily basis.... 😭😭😭😭😭 IF I rent out a car again I have being told that I will b paying R295 per day I am so disappointed because I am paying the monthly installment of of R5400 and insurance of R1200 but I am being told to make a plan for myself, JUST BEACUSE NISSAN CAN NOT PROVIDE ME WITH THE PARTS.

I wonder how possible can a company introduce a car n can not provide with parts....
