Hyundai South Africa has no replacement parts

I was in a car accident on 9 March 2023, and now 3 months later, my car is still not repaired. They've had to order parts twice, and every time the parts are on back-order with a waiting period of 21 working days. Now they saw the seatbelt needs replacing, and instead of getting back my car this week (3 months later), I need to wait another month as this part is ALSO on back-order for 21 working days.

Insurance companies only give a rental car for 30 days, so I am without a car for 3 months out of the 4 months.

When I bought my Hyundai, I was not made aware that parts are nearly impossible to get, would not recommend anyone buying Hyundai unless you want to wait months for your car to be repaired after an accident, due to parts availability.
