Auto & General failed me and i could loose my job. no assistance on car repairs

I have been failed by Auto & general Insurance, they recommended Potch panel beaters as a suitable vendor to repair my car after my accident on 24 Dec 2021. The process has been a nightmare. The panel beater has had my car for almost 2 months now and thus far i have not received my car and have no commitment from them on when i will get my car. Auto & general did this even after they saw all the bad reviews connected to Potch panel beaters on all google & social media

They are the most unprofessional unreliable panel beaters i have ever come across. they have had my car for almost 2 months and you can never get a straight answer out of them. Auto & general insurance sent my car here after my accident on 24 Dec 2021 and to date i still have not received my car. they promised to be done by Friday 28 Jan 2022, then they discovered additional damages and needed extra parts which would be delivered on 11 Feb. 2022, then the parts are not delivered and i will get the car on Thursday 17 Feb 2022, now they still don't have the parts and i might get the car on Tuesday 22 Feb. 2022. you can never get a straight answer, they always promise to call back and they never do. you literally have to call to ask a question and call again to ask for feedback, which you will not get then call again for feedback on feedback

The bottom line is I have been given a warning that if I am absent at work disciplinary action will be taken against me and I could potentially loose my job as a result of this whole process. I have delayed my car hire and even extended it because I could see this was taking much longer than expected but at this point I'm out of options and my job is being threatened. And auto & General is not assisting in any way. What can the insurance do at this point to assist me as I need a car to travel to and from work? If I am absent I will be dismissed?
