Outsurance treats 3rd parties unfairly

I was driving on Lynwood road from the West side heading towards the East, one of their clients made a U-turn in the middle of the road and I bumped into him, he admitted that he was wrong, we went to the police station and opened a case and I was told that my car would be fixed by Outsurance, they are fully liable, a week later, I am still waiting to get a claim number, was told that their legal is going to contact me, never received any such call, took the initiative and called them myself, they greeted and they told me that they are going to get an advisor to call me back, my car is sitting in a storage and the cost is building up daily, they have not sent an assessor to go and assess the car, they say that I must pay the storage myself, "I am not a priority because I am not their client", I have a chronic disease called lupus and I battle inflammation and I explained that to them and asked that they at least give me a courtesy car in the meantime while they are busy processing the claim, for health reasons, as I also have a shortness of breathe issue, they said they will not, after their client risked my life, they are putting my health and job at jeopardy, because I am unable to work without a car, they are not the least bothered,
