Had the car at the panelbeater for 8 months after an accident on the front

Had the car at the panelbeater for 8 months after an accident on the front. The repairer failed order necessary parts. They told me the car would be ready 4th of May, while they knew they didn't order the parts. Till now I'm still waiting. Both insurer and repairer refuse to offer a courtesy car for the inconvenience and unreasonable delay. I have been paying since July 2025 for a car I'm not using. None of them are transparent. The consultant whose in charge of my case, only follows up when I call... I've never had a call from him actually updating me on something I don't already know/told by the repairer. Not acting in my best interests. I've suffered emotionally and financially. The original estimated time was supposed to be 8 weeks. It's almost a year now
