Bad ownership experience

I own a Haval Jolion, which I bought in 2021. I got involved in an accident in October 2022 and till this day I haven't received my car due to all the car parts that were needed and still needed to repair the car, were all put on back order. Haval SA claims to have a warehouse in the country, if they do I don't think it's car parts that are stored in there, because every time the repairer ordered the needed parts, they took more than two month to deliver. Surely they store fruits and vegetables in that warehouse and not car parts. My car is still with the repairer waiting for a windscreen glass from China. To show that they don't care, in this 7 months they failed/refused to give me a courtesy car.
